PA Hardwoods......

Use Actual Draw weight, hard single cam and shade toward the stiff side when choosing shafts for that bow. Plug in your actual draw weight and if you are borderline go with the heavier spined shaft.
At 65-70# you will be Wayyyyyyy underspined with a 29" shaft and that set-up. You are going to be shooting one of the fastest single cams on the market in the Patriot so if you already know you are underspined for your current bow I wouldn't plan on being so lucky with the new one.[:-] You already know the answer right? you just don't want to drop more coin on new arrows?

Jump up to a 6075........At 30"/70# I shot 29" 6075 Terminator Hunter selects 's from my Patriot SC with a 100gr head and they tuned beautifully and flew like darts.

What's your draw length?
