I also use relatively large hooks on the OP and am a C&R advocate. Nothing smaller than a 2/0 under normal water conditions from February to April. I use the larger hooks because I miss less strikes and when I do hook up I can apply more pressure/bring 'em quicker because of the increased gap/holding power. Of course I'm using 15-20lb mainlines and the the larger hooks balance out these drift fishing outfit better too. I'm not speaking for Rich these are just my thoughts to your question CF.

2/0 w/ rags

3/0 w/worms

4/0 w/B-2s
