I like WOODSTOCK BRAIDED DACRON IGFA Fishing Line with a fluorocarbon leader
Comes in 12 pound to over 30 pound test and it has been water proofed
I also use WOODSTOCK tip up line, I use the 200 yard spools on my lake trout tip ups.
E bay has a nice selection of WOODSTOCK products.
I also use a mono backer to insure no slipping on the reel.
Good Luck All
