I use the same ones I use for steelhead, seem just right. A hoop that is in the neighborhood of 24x20 with a reasonable bag depth works for me. When wading, I slide them up on the bank. I also use a tailing glove-usually employed on salmon and steel- to hold them still and control them. If they're run-of-the-mill (no pic), barbless hooks get them released without even taking them out of the water- you'll rarely hook them deep. No sense giving them a rock massage getting them unhooked and released, tough though they may be.
Best of luck, they are truly a blast to fish for. I'm a rank newcomer to this forum, seems like there's a great knowledge base here.
