they give me a base to start in the instructions,so that should help.I just thoght maybe someone found the magic helix angle to run with them.I have heard guys say straight 43,stock 47,a few different multi angles.I bought another primary to stick these weights in,that way I can leave my heavy hitter setup all together in the other primary.I am looking at doing comparisons between the heavy hitters and heel clickers.I know the team made my heavy hitter setup very strong,just needs a little tweaking on top end.Now I want to try the heel clickers with the team and with the stock secondary,see how the 2 compare.thanks-Harvey
