Kegan, I have 600 RAMIN dowels and about 100 DUG FIR 85 # spined shafts left, those with 190gr broadheads and left about 29-30" long come out in the mid 800gr range.
the alluminum ones are 2117's filled with 1/4" tubing, than you can play with all kinds of weight up front with those
2 of them are IPE arrows that RICK from Paleoplanet send me, those are over 950gr
