Is 6GPI enough?
Hello, I have a 1999 Hoyt powertec, shooting carbon express terminator 6570's ( does this mean it is good for 65 to 70 pounds) that was what i was told, just confirming, I have these arrows cut at 28", and a 100 grain field point which was replaced by muzzy 100 gr. 3 blades but they hit the riser, so I bought 6 brand new NAP 100 grain expandables to stop that problem, I believe my arrow is a around 10 gpi arrow, just the regular terminator 6075, so if it was 10 grains, it would be 280 plus 100 for the tip so I'm at 380, without the insert, nock, and fletchings, which I don't know the weight but it comes from the factory with them, my question is will this setup be too light for a 60 pound bow, I mean without causing damage? is the 6 gpi im getting good enough, i believe its at 6.3, but I just don't want to be too light and make my bow pretty much like dry firing it

Absolutely, you will be fine. I'm just over 5 grains per pound with no problems what so ever....At 6 grains per pound you are fine....and your arrow is likely heavier than you think it is.

Carbon Express makes Terminators in 2 sizes 4560 and 6075. I'm assuming you mean you are shooting the 6075. In either case, the terminator arrows are very heavy arrows. The 4560's are 9.5 grains per inch while the 6075's are 10 gpi. I'm not sure where you got the 6 gpi figure from. You can check the Carbon Express website for their arrow setup guide. The 6075's aremuch too stiff for your setup. As far as total arrow weight you have nothing to worry aboutsince you are probably over 7 grains per pound of draw weight. Like I said, Terminators are some of the heaviest carbon arrows you can buy.

Your arrow weight is just fine. I shoot near 7 gpp and love what they do to whitetails. Stiff spined arrows tend to fly fine out of compounds when you use a release. The only thing I'd do differently, would be to put on a heavier head. Your FOC on that heavy arrrow won't be very high with a 100 gr tip. When shooting broadheads, higher is better. A heavier head will weaken the spine and increase FOC. Both things that would benefit your setup.
