Not sure really other than success... I probably shoot as many or more arrows per year than anyone on this forum, but really can't say one feature that attracts me to certain bows... Kinda odd if u think about it. Thinking about it over all tho, I would say that a rock solid back wall is VITAL to my shooting style. I shoot backtension, with a hinge, so a good wall with no sponge is what has to be a part of every bow I shoot.
