I float tube mostly in salt water in the inlets, bays and harbors or anywhere that entry into the water can be done without getting wet or puncturing my tube. Certain tackle is necessary from a tube. I have completely abandoned the use of conventional reels . Spinning reels handle very light line much better than conventional reels . Sure, you can load 2,4,6, and 8 pound test on a conventional reel , but you better not backlash.
Backlashes always kink up the line and that is a disastrous situation with light lines .
I fish from the bank and a boat in all the trout lakes using 2 and 4 pound test lines . This is not unusual as most all lake trout fishermen do the same. The point being though, is that you never see anglers on a lake using conventional reels , unless they are trolling. Lately I was on the end of a deal to test the new Team Daiwa S spinning reel . I tested the TD-2500CU aluminum reel .
