I shoot 29.5 400 with Tracer nocks. Great combination!

I shoot the 340's with blazers, love em. They shoot great.

I shoot the St Epic 400's at 28.5 inches with blazers out of my Mathews Drenalin (68lb @ 28.5 draw)with Muzzy 100g heads. I have the50g inserts in them to bring my FOC up and they certainly fly well and knock deer down very well as well.

I shoot 'em.....love 'em. 400's with muzzy's.
