Ah, thats why, thanks for the answer. For me as non-hunter a 64" bow is quite short. I like my bows in the 68" - 70" range. Therefore I keep the inner limbs a tiny bit stiff and make the outer third of the bow bend nicely (with stiff tips). But thats just personal preference. I have to try your system once, if it gives more speed, then it's surely worth a try...
Keep on buidling
