RE: conviece me which brand to buy
I will agree with the above statement. Speed does not always equal accuracy. Now if you are trying to shoot out to 60 yards but estimating the range, then speed will help with judgement errors. Although I don't know how much at that range. As far as accuracy though, I have shot bows closer to 200 fps with heavier arrows pretty accurately at 70 yards and beyond. As long as you know the range and have sight settings for it speed does not matter.
I personally am very happy with around 230-245 FPS. If I could get a bow that shot faster I would most likely up my arrow weight until I fell back in that range. I'm not concerned with 3-D though and I don't stalk hunt. And as far as target shooting goes, I don't even concern myself with speed. I bet I was close to 200 fps shooting spots. However from what I understand with long distance shooting speed and weight are a consideration because of the wind.
