Nailed the grain window, I’ve had some fun with lighter flies & mono leaders at 450 grn, and the 540 fist is a dredger on it.. I like it!!! Bought a 7110 Z-Axis 2-3 years ago. Wish it was a tad longer. Fun rod. Not a big fan of the long rod Spey game but switch is becoming more my thing on the river…. Especially has my shoulders age…. What grain windows you throw on this mad Red Baron? 480-540 ?
