The thread is mistitled "7126". I have the 7136 Z-Axis.
I tried out both the 510 and the 480 gr. Rage. The 510 gr. Rage is decidedly skagity on the 7136. I liked the 480 gr. Rage best. It'll throw a light tip easy, and feels low-effort.
Given the feel with the 480 gr. Rage, I suspect a 450 gr. Scandi would cast nice. Maybe I'll give that a try tmr.
