Thanks for all the input. I think im going to get the 8 inch. it just concerns me a little when im targeting pike and lake trout but you can get a pretty big fish up an 8 inch hole.
I finally found a good setup for storing my ifish pros, it is a tough tote made by styleworks, got it a Walmart for $18 it is the 10.5 gallon one. holds everything I need to go tip up fishing except for the rods for the ifish pros.
