evening all, got a bit bored earlier and started comparing my bows. all bar 1 are 45# the other is 32#. all bar 1 are 31/32 mm wide at the arrow pass, the only different one is my first elb which is 27mm at the pass. how much difference in arrow spine would 4mm make?

well, at 20 yds the 4mm slimmer bow moves the aim point about 3" closer to the gold, I think if my next bow is slimmer and faster it may be pretty close to aiming at the gold : )
