thanks alot paul reallly informative..i was wanting to mainly use this setup for hunting and just target shooting like practicing before i go on the hunt... i have a set of 500 26 in arrows but i was thinkin those might be to weak right and i might have to drop my poundage a little.. i also have some long ones like 30 inches @ 400 spine..i was thinkin of just cutting them a couple of inches...cutting them will make the spine stiffer rite and the longer the arrow the weker it is ?am i correct?
