Because I can.

LOL!
That's what the forums are for, right?
The only difference I've found in 100's vs 125's is in tuning my bow. Really, at hunting-distances, 25 grains isn't going to make that much difference in speed or penetration. I shoot 100's on one bow, but my back-up bow shoots with the 125's a little more consistantly because I turned the poundage down a bit, and so the arrows I had were a tad over-spined. But I agree that if you want to shoot mechanicals, there's a little better selection in 100's.
