HuntingNet.com Forums - Speed Bows~~ Heavy/Light arrow??

I am just wondering...I have no intentions of purchasing! I just read the lil debate over speed bows 320+ shooting accurately.

I am sure it takes a little work to get them there? I am just wondering if you were to shoot a heavy arrow out of a speed bow and drop its speed to 250-260fps is it going to be ANY MORE accurate then what it can be shot at 320+??
I know there are going to be variables such as arrow,bhead, etc.... but im thinking if you were to go all out with Top of the line everything from both speeds??
