I currently own a Hoyt Cybertec(split-limb), also an older Hoyt Viper(split-limb)and I have owned a Mathews Q2XL. I can't tell any difference to be honest and I do't think there is any advantage or disadvantage to split limbs. As far as busting limbs---I busted a bottom limb on my Q2XL. It busted right in the middle of the limb and I was at full draw at the time. I believe that it was my fault though. You are supposed to back poundage off when pressing bows-I never did a I think I weakened the limb.
