Just tried out the 125 gr.

I couldn' t screw them in! The inserts in my shafts are too deep and the threds wouldn' t catch. I had to take them back. We really tried to get them to work but no dice. I was trying them in my epsilon sme Heavy Shafts.

We tried them in Vapors and they only screwed in 7/8 of a turn. Not to confidance inspiring to hold them in.

Tried them in easton, and carbon impacts, a little better but not much. Looks like they made that new collar but didn' t adjust the length of the shaft to accomodate.
