My experience has been limited to wood Bear trad bows shooting off the shelf; and I have not shot any of the aluminum risers, but I have been thinking of buying something along the lines of a Dorado, or an Excel set up with TradTech limbs, maybe with a plunger and flipper rest, for hunting. (My draw length: 28".) I will probably start out at 35-40-pound limbs for practice, but could graduate to 50-55-pound limbs (for hunting the fairly big and tough wild pigs out here in California). These are lightweight aluminum designs, of course (as distinguished from something heavier like the TradTech Titan III riser). My specific question for you folks with wider experience is: do you think that these lightweight aluminum riser designs have more vibration or hand shock -- maybe too much -- at the heavier weights above, say, 45# ?
