I'm just getting into 3D. Wanted to get an opinion on Gold Tip X-Cutter arrows.

I shoot a 26.375" arrow @ 60 lbs. I was planning on getting a set of GT X-Cutters with a 90 gr tip, GT Nocks, Vanetec Super Spine Vanes. Total arrow weight is ~346 grs.

Since these arrows only come in a .250 spine, will this setup be too stiff to shoot?

Any other arrow recommendations would be greatly appreciated.
