Hmmm, good question. I own both, well kinda do. My 54# Chek-Mate is an r/d bow and I really like the way it shoots. My 47# Don Brown Bamboo with Osage belly LB isn't a glass bow and there is some minimal string follow designed into it but it is as close as I can get to a straight limbed bow and I really like the way it shoots, lol. I guess if I had to get right down to it and make a choice as to which one I prefer, it'd be the r/d bow. Less shock to the elbow and hand on my bow arm. I don't see any difference in accuracy and speed is right up there on both with properly spined arrows weighing 10g per # of draw.
