Anyone else have any experience with these arrows?
I just shot some (full size), and they're incredibly fast. They're VERY light, but advertise a very stiff spine.
I'm shooting Easton 300's at 10.7 gpi, and I'm at 285 fps.
These arrows (again, full size) were clocking in at 335 fps.
I didn't notice any difference in noise or shock/vibration in my BowTech Tribute at 70 lbs.

I am worried about them being too light...any thoughts??
Thanks!
