RE: Dozen under $100?
I think you're on the right track with Gold Tip.In my opinion, you can't beat them for the price. The XT Hunters are well under $100 so you can buy a few broadheads with what you've got left over. With your setup you could either go with the 5575 or the 7595.
Personally, I used the 7595 last season w/ a 125 grain broadheads. It was a little on the heavy side, but my bow shot great. I'm going to give the 5575 with 100 grain heads this year to pick up a little speed.
In short, I don't think you can get a better arrow for the $ than Gold Tip.
