I had to download ontarget2 today. My computer self destructed on Saturday. Or maybe I helped a little. But that's ANOTHER story.
Someone at Pinwheel Software must have found that the GT500 produces much more Ke than they originally thought.
With the new version, my CX 4560 arrows are WAY too weak. They were only VERY SLIGHTLY weak last time I checked.
Even if I take weight of the fletching and weight off the tip , it's not what I would consider close enough.
I've had several conversations with people here on OT2's arrow recommendations. THEY HAVE CHANGED.
I need to buy new arrows......I haven't told my wife yet.
So I put together a small chart to reference with the newer spine numbers for the GT500.
------27---- 28--- 29--- 30 DL's
60lbs .4308 .4104 .3906 .3715
65lbs .3919 .3750 .3584 .3423
70lbs .3595 .3452 .3312 .3173
Now, go buy new arrows......It'll be a good excuse.
