I bought the same one this season. Stick with 100gr, I have and shoot/shot Slick Tricks and Wasp Jack Hammers (mech) Had success with both heads. I use the aluminum arrows supplied as a discharge arrow alonf with a dull field tip and the Hornet discharge block $19.99 at cabella's and bought the Ten Point Carbon Cross bow arrows- HEA-620.6 Carbon 22/64 20" SB CAP w/Vanes and am very satisfied with the set up. Good Luck.

PS. I now also carry one any old broadhead for a dispatching shot if ever needed , rather than use one that I hunt with.
