RE: what is slow to you
I just chrony'd my 70 lb. UltraTech and it's shooting a 500 gr. arrow at 250 fps. I consider that moderately fast. My longbow shoots the same arrow at 190 which I also consider moderately fast (for a longbow). Now my 3-d rig shoots a 300gr. arrow at 325fps., that's rediculously fast. So I guess my answer to the question would be; it depends.
I think most people would be surprised if they actually shot their bows through a chronograph at how slow they are compared to what you may think they are. Big bulls hit it on the head though; it's all relative.
