Thanks. I won't use any body grip smaller than a 220 for fisher. I had an incidental fisher wearing my 160 around his throat. I was able to release him, sounding like a horse as he thundered away. Our 220's have to be located either at least 5ft above grade, or recessed within an enclosure from 8 to 15 inches back, depending on the opening size of the enclosure. So I'll stick with the leaning pole sets using body grips, but I thought I'd experiment with a cubby and footholds. I just don't want to use the wrong size and screw things up. Their paws aren't real big, and I don't want a leg catch. Maybe there is no size foothold trap suitable for fisher. You're right, they are very powerful. I guess that's why I'm asking.
