Rob-
To answer your question, both bows are 68" long with a 28"draw,cocobola risers, one is 55# and the other is 50#'s. The difference is 5#'s and without using a chronograph the carmelized seems to be quicker as the arrow doesn't drop until I'm further away from the target. I usually buy my shafts between 340-360grain, but I haven't grain weighed these shafts yet.
I was just noticing a difference with the new bow that I'm very pleased with. The carmelized limbs seem a little stiffer almost like how carbon on the limbs of a bow feels. On another thread I asked Leatherneck what he thaught of his new bow with carmelized limbs, since he doesn't have another Hill to compare it with he couldn't make a comparison, but he did say that he is very happy with the bow.
My next bow will be a Tembo stringfollow with a carmelized limbs.
