Are you looking at the MHM or MHMF because they are slightly different.
Its very sensitive but I will say I fish mine a little faster probably but I can feel every movement. The power is probably what I like most about it. Ive had fish get stuck in heavy weeds and never had an issue pulling them out.
I've never fished with copoly before but I use #15 Tatsu fluoro and havent had a single issue.
