In another thread the bare bones of a decent discussion was forming about limb and bow lengths, what the theory is and what the real world effects are to different archers.
GT had implied that japan were making good use of the new extra short limbs now available for short draw shooters from hoyt.
I had asked what configuration these were being used in, ie were they being used with 25" risers or 23" risers and what differences were the archers finding.
The thread was locked before GT could respond but I was asked about my own experience which I'd said had seen little to no difference between a 66" and a 68" bow so In an atempt to have a discussion about archery I hope this starts the ball rolling.
I'm a fita target archer, I rarely shoot field but have never shot 3d, as such I only need sufficient speed to reach distance with a given sight mark.
I shot a 66" bow for two years and followed the advice of Border archery to set it up and it consisted of
Inno cxt with short hex 5's 38lb wound up to give 40lb OTF 14 strand fast flight string with a 7 1/2" brace.
I was in need of new limbs (but not borders) and it was suggested I try a 68" bow, everybody was raving about the inno limbs so I took the plunge and ordered a set of mediums.
I was told by all that longer bows are slower, innos are slower than hex 5's that new 16 strand string will be slower raising the brace height will rob you of speed.
So I prepared to take a bit of a hit in sight marks, the new set up consisted of
Inno cxt with medium inno primes 40lb giving 40lb OTF 16 strand fast flight string with 8 1/2" brace
I didn't chrono either set up but set out using the same sightmarks as a starting point and at 90m there was a slight difference in favour of the innos (nothing worth writing home about) and all the others were the same.
I kept the same arrows, clicker position, tiller and nocking point and my tecnique didn't change, I've been shooting the same set up for two years now.
My groups were better from the start as well and they felt better to shoot.
I don't generally use groups or scores as a means of judging performance as new kit does generally give a temporary boost but it's always reassuring that there's no drop.
The sightmarks however seem to fly in the face of conventional wisdom.
What experiences have others have changing bow size?
