Line twist and line memory are giant problems when Ice Fishing. Your hands are cold, the light is poor, especially in a shelter, and it is harder to see the minor twists and coils that prevent good bite detection. For this reason alone, I switched to 10# braid with fluoro leaders. I can see the line as it enters the water, it always goes STRAIGHT down the hole with no coils, and twist is almost eliminated!
Using de-greased baitcasters has eliminated all line twist, and the drag is so much better than on most spinning reels.
Yes, I admit, it does ice up more than some mono lines, but I'll take the advantages of braid over the drawbacks of mono any day. Another advantage of braid is that it doesn't nick like mono, and get weaker. additionally, braid doesn't degrade over time nearly as bad as old mono.
In open water, I use the same setup. There are certainly disadvantages, like wrapping around the guides, and knots that are almost impossible to untie, but I still feel like aIl spend less time fussing with it than my friends who fish with staight mono- it casts a mile due to smaller diameter, sinks faster than mono, and doesn't break after contacting rocks.
There is a learning curve, and some friends can't adjust because of frustration that it doesn't work like the mono they've been using all their lives. I originally switched to the braid/topshot for saltwater kayak fishing, and it's advantages were so amazing that I switched all my freshwater set-ups about 10 years ago. For instance, 10# braid is the same diameter as 2# mono, so I can get way more line on the reels than with mono.
Never going back to straight mono--
