Just remember accuracy is the most important thing . It doesnt matter how fast or how hard you are hitting if you cant hit what you are aiming at. In my experiance I have found that anything that shoots over 270 is fast enough. I recently baught a BowTec Patriot it was shooting 320 in a longer draw but I was having accuracy problems so I shortened my draw the accuracy came back and my speed went down to about 307 its still realy fast but now accurate too.
