Default Am I underspined???

Set up is 29.5 inch draw 71lbs out of a cam 1/2.

Goltip 5575 @ 27.5 inches at 380 grains yields on average thru chrony 289.7 FPS and 71# KE.

Goldtip 5575 @ 29 inches at 392 grains yields on average thru chrony 285.6 FPS and 71#KE.

Are the 5575's spine enough for this set up?

Also I will be picking up an extrme vft this weekend. @ 70# will the 5575's be underspined on it? Should I buy some 7595's or is that over doing it?

My personal preference is to always err on the stiff side, especially if you'll be flinging broadheads. Just seems to work better for me.

5575's 26.75"arrow 61.5ft/lbsKE = slightly underspinned. I don't even think the camo 5575's will work for you, you need the 7595's. It'll only be 20 grains and you'll hardly lose any speed.

I just ran you through TAP and show the following:

The 5575 is way to weak even at 27.5" The 7595 @ 28" appears to be a very good match. With the VFT you will also be glad to have the stiffer arrow. My PRO 40 requires a stiffer arrow than the norm.
