Am i Under-spined?

[resident vs nonresident]

ya I may take few of my well used “practice “ arrows and cut them down shorter just to test it.
But otherwise current set up seems to work fine as it has past 2 seasons

I shoot a mathews halon 70 pounds at 29.5" and moved from 300 spine to 260 spine this year. My broadheads are 100 grain and I noticed a considerable difference. TAW is 524 on my hunting arrows and 495 on my 3d arrows. Arrows are cut to 29" just past my rest. I'll never go back to 300 spine arrows.

It is very, very impressive to have a bow shop Tech shoot it through paper to get a fletched field point tune on the bow, and the bow can then be handed off to a newer shooter and it is tuned well enough to shoot fixed BH and field points together at 60 yards.
Keep that Tech happy, you don't ever want to lose them.

No drifting if im shooting well that day.
With new string on shop tech that bullet holes punched so paper tuned.
Again: I didn’t have any issues up to this point. But just wondering if I could be under spines and if it’s worth trying stiffer arrow?

With a 30 inch dl, you could stiffen the spine by cutting 1-1.5 inches off the back since they are inserted up front.

You could shoot a 28.5 carbon to carbon and possibly a 28.
