No, I guess I figured that there must be stiffer arrows. I know that the 7595 is as stiff as GT makes them, but If I can buy a bow with 80# and even 90# of draw weight, there must be arrows to buy for them.
Boy, do you have a lot to learn. Try looking at the spine of the "300" Ultralite. Look at the spine of the UL22 series. Maybe the X Cutters or the 30X.
Expedition and XT 7595 is supposedly a 340 spine. They are mostly what you see in shops because that's what shops can sell. That doesn't mean GT doesn't have stiffer shafts.
