Clam flipover style are said to be better, but their disadvantages outweigh their advantages to me. #1 issue, if you walk out, they're ridiculously heavy. Call me a pansy, or lazy, but i dont physically drag my boat to the lake on a trailer to go real fishing, why would i drag a 400lb cube out for perch and crappies? The popup tents are 20lbs, and set up just as fast or even faster than some flipovers.
Ive been using the ctc stuff for years . Ice fishing is very cheap to be successful at.
