Kevin.......er I mean Ken.


Those 5575's might be stiff enough if you shoot without a point.[:-] But then we might be running into some weight issues.[8D]
(Speaking of 5575's........at the show I saw a stripped down 300gr 5575 with no point flung out of Kevin's "Prototype" just for giggles. At that 29 1/4" and 69# I think it was pushing 390fps.[:-])
Take that Gold Tip chart and spool it onto your toilet paper dispenser when it comes to the Pat Dually. 7595's for that bow, no less.
CE Terminator HUnter Selects at 6075, A/C/C's 3-71's etc etc. i'd try those Axis arrows as well........Jeff could recommend the proper spine.
Remember that bow is NOT behaving like any other 70# on the market. It's a powerhouse that requires a little extra common sense when choosing the proper arrow spine. Err on the heavy side and you will have more options.
I'm not sure I'd shoot a 28" 5575 out of a Pat Dually at 60# .....GT's chart has always seemed "soft" to me. If you are even CLOSE to the higher spined shaft, pick that one. In your case though it's a no brainer. 7595's for sure.
