Can't hurt to give it a try. What don't you like about trebles? I run small ones, #12 for eyes, usually #10 but sometimes #8 for pike. They normally end up in the corner of the mouth and come out easy.
Honestly, I like circle hooks. I may lose a few more fish, but to me a circle hook is perfect for a tip up as the way to set a circle hook is let the fish run for a bit, then just add a bit of tension. I also never gut hook a fish with a circle hook. So I say go for it.
I don't think anyone I fish with uses treble hooks on their tip-ups. This could be a regional (Maine) approach since most the videos I see on youtube from out west or Canada seem to use treble hooks.
Gamakatsu's finesse wide gap in a 4/0 or 5/0 is the only hook that you'll find on one of my pike tip-ups. They work equally well with 4-6" suckers or similar sized dead smelt. I hook my baits inline with the spine just behind the dorsal fin. My number of dropped bites has went down dramatically compared to the #4 trebles that I used to use.
single siwash on all my spoons.
