I am cuurently shooting a mathews prestige for my 3D bow with a 383 grain carbon express maxima 3D select arrows with a 28 inch draw lenghth. At 64 lbs it is shooting 283 fps. Im looking at getting a conquest 4 but people have told me it want be fast enough for me at 28 inches. I will be shooting carbon express line jammers which will be lighter but i still don't know if i will get 280 fps out of it. If anybody has any advice i would really appriciate it.
