I will keep at it until my bow is as deadly as a gun from 25 yards or more.What should my brace hight be?I figured I`d loose an inch or so from my compound draw length,where should my anchor point be?With carbons,what spine to use,could I actually be over spined with 45-60`s or 60-75`s? does the length of my arrows still matter or could I use a 30 inch arrow and still have good arrow flight?
