Our wild trout can reach 20"+ on our local steam. High pressured water requires nimble feel, and perfect presentation of the right fly pattern. The MKII 11' 2wt is ideal most bugs, but especially the little bug game, and micro leaders. Had the chance to fight several larger trout in that 17"-20" category. Taken a few rides to trust the deeper bend on the longer lighter rod, but surprisingly strong spine with the bigger battles. Would not recommend as a do-all rod for swift water, dry flies, indicator fishing or heavier beads. It is the right tightline tool for our super technical river, in moderated seams and riffles, with our rich entomology. So far so good.
