all depends on the rods you use!!!! light noodle rods I go light usually 2lb fireline with a 3-4lb floro leader, if you only use floro for the leader you dont have to buy the expensive stuff, (difference between expensive and cheap floro is not breaking test but usually how it comes off the reel ie, line twist or smoothness)
stiffer rods I usually go up in line to 4lb test and allways use a leader! length is based off water clarity 1-2 foot for panfish 3-4 foot for walleye and 4-6lb test line usually.
I really up the the line weight on the rattle reels/tip ups (18-20lb test) for a few reasons.
1, you dont play the fish much. I pull up line “hardish” and fast to not give the fish slack, you wont loose as many
2,usually get mix bag fish on rattle reels more so than jig rods, ie eelpout and pike etc! you wont regret heavy line on them
3, less tangling with the heavy line
4,with no rod to absorb shock 18-20lb mono provides more give to keep that hook in the fish! YEP I SAID IT, 5-7 FOOT OF MONOFILAMENT LINE WORKS BEST ON RATTLE REELS! avoid floro on rattle reels you want the stretch in mono!
