    If you were to measure the served bundle of 24 stand 452X and 24 stand 8190 there would only be about .005" in diameter difference. The 24 stand bundle of 452X served with .014" Halo is approx .110" dia and 24 stands of 8190 served with the same .014" Halo would be .105" dia. That size could also slightly increase or decrease depending on how tight the bundle was served. The 8190 is rock solid material and as Breathin mentioned, 24 stands holds like a rock.
    In all reality, a good set of strings regardless of being made from 24 stand 8190 or 26 strand 8190 comes down to who and how they were made.

    The following is right off BCY's website.

    Question: If I reduce the number of strands to improve arrow speed, should I be concerned that the strength of the bow string is reduced and therefore dangerous?
    Answer: With almost all modern materials used in the manufacture of bowstrings, the strength is well in excess of the maximum tension applied to the string. Consider this - A popular number of strands for Formula 8125 material is 18. The breaking strength of a single strand of Formula 8125 exceeds 90 lbs. Using 90 lbs as the criteria; the total strength of 18 strands is over 1600 lbs. Of course when set up on a bow, the strands are split at the loops and a static load test shows that approximately 40% of the strength is lost at this point. This still leaves a breaking strength of close to 1000 lbs.

    It has been calculated that on a high poundage bow, say 75 - 80 lbs, it is possible to generate approximately 200 lbs total tension while drawing. Compare this to the breaking strength over 1000 lbs mentioned above and there is at least a 5 - 1 safety factor.

    Reducing the number of strands is normally ratioed to the draw weight of the bow, therefore on lower poundage bows, the 5 - 1 safety factor will remain or perhaps increase.

    With the newer, smaller diameter materials like 452X and Trophy, the single strand breaking strength is less than 100 lbs but many more strands are used so at least a 5 - 1 safety factor is maintained.

    Basically, using the manufacturers recommended number of strands x the breaking strength of the string, will assure you have a string with much more than adequate strength, and if you decide to drop a couple of strands to increase speed, the strength of the finished string will still exceed the maximum poundage generated by the bow.

      I agree but has anyone done testing on what happens on the shot? When things come to a screaming stop. I wonder if there is anymore load on those end loops. another thing I think thats being over looked is the fit in the cams groves. Then the weight of the strand count will also effect speeds. (See speed nocks)
      No ifs and or buts Just maybee.

        Finished diameter of the strings will also affect draw length/weight/letoff as well.

          With regards to finished diameters of the strings as well as weight, the variance in the wax content of the stands or the color combo used (flo colors vs black white or natural) will be a contributing factors in the finished strings. Different string builders finish their end loops differently or prefer to use certain serving materials on the end loops and again it will have slightly different effects. Some builders may serve their end servings on the string not as tight as on the cables to minimize peep rotation, yet again their will be slight differences in how the string fits the cam grooves.
          If Elite is going to expand their warranty restrictions to allow alternative products such as BCY 8190, Asto or SX2 to used as string material they also need to allow for and specify some variance or tolerance in the strand count and served bundle sizes based on the contributing factors yet allowing string builders some flexibility in producing quality safe string sets.

            My take on this is that the 24 strands of 452x is slightly large for the track, and 24 strands of 8190, being only a few thousandths smaller finished with the same halo serving, is much better. My personal bows, Elite or non Elite, will be sporting 24 strands of 8190 from here on. If that kills my warranty, then so be it. I will advise anyone I make strings for of the rules set by Elite, but I will run 24 strands on my stuff...

            Thats about all I have to add to this...

            Well, one more thing.... Way back when elite released there tuning vid, they said that .100" was the goal for diameter, now saying that between .100" and .110" is the range. 24 strands of 452x is usually about .105-.107" for me depending on colors, and 24 strands of 8190 with the same servings are coming in just a fuzz(.001-.002") under the .100" mark.

            I would ask that Elite re-evaluate their standards on this and allow 24 strands of 8190... Even if they think this is too small, I don't believe there is danger of it hurting the bow in anyway.

            Pete, if you see this, shoot me some colors you like and info on your personal bow, and I will send you a set at 24 strands of 8190, I promise you will love it!!
            Smile!

              Will the smaller diameter string cause the bow to loose speed even though the string is lighter due to the string being taken up slower during the shot, I may be thinking way off here but the center of the smaller diameter string is closer to the center of the cam which reduces the diameter/circumference of the cam. would you benefit from fewer strands with a larger diameter end serving to bring you back to .110.

                  Have no proof but something slows them down. I do know it takes more speed nocks to get the speeds closer. but 22 strands of 452x isnt as fast as 24. I tried it and lost 6 fps.

                            Im using 8190 on both my bows (Strother Archery) and the stuff is great!
                            Both my bows picked up 3 fps compared to 452X.
                            The 8190 is alot nicer looking, brighter colors, and I have yet to wax either of my strings in 100's of shots.
                            Was told not to wax it, and if I did use very very little wax.
                            Thus far no need to wax, they look like new!

                            Tim knows how to make awesome strings!
                            8190 is great!
