I shoot easton powerflight 340's now, 28" with 100 grain field point and the rage bh. Any body shoot these? I have a WB, would these be to narrow/small/thin to work properly in the the biscut?These eastons are 9.3 gpi, shooting 27" and 60#'s on the X, actual speed, no clue. These do seem heivier than the typical arrow used to test bow IBO's.
