Good posts. I also use high vis line w/ fluorocarbon leader, 2 pound test. Reel magic keeps the coils from getting too bad. Also, I use my own home made springs that are very sensitive. Often, a crappie will create slack in the line so I'll either see that or my spring actually go up. Anything different than what I expect, I set the hook. Sometimes, I may not see anything or feel anything but get a whim that a fish is there and set the hook...many times that works.
Don't own an aquaview, but I can see a real advantage. Might try to get one this year. Better start saving $
