Harrison is tough. I think the best bet with Harrison is putting in your time on the ice. I've only fished it a few times and neither time did I do too well. 7 guys, 3 lines/guy, 4-5 hours, 1 brown about 18". I've seen some big fish come out of there, but I don't know that it is hot action very often.
Also, that wind sure puts a lot of sand in the ice. You'll go through auger blades like nobody's business
We had 3 augers between the 7 guys, after 1 hole each, the augers were dull and getting through 12"+ of sandy ice with dull mora's is no easy task
I've since thrown my mora away and am very happy with my 6" lazer (unless the ice in thicker than 18", which on the lakes I fish isn't too often)
