it's tough!
and with the manufacturers redesignating their `old' lines and new lines coming out on the market i'd sure hate to try and tell anybody what to buy,shops like the Redshed have tryout lines,my suggestion would be to get a mid length belly in two or even three ratings then compare those back to back,,,find a big feild, cast all three lines out,one at a time,laying each out with room between them,to the side,slip the but end in thru the tip down to the ground,pull in to the end of the belly then just cast one after the other and back to back ,that's what did,i'm not saying that's the ultimate way,casting with somone who's completely familar with `your' rod would be the best,hmmm,is the problem that you have an overlined rod?,it can't handle the line wt?,i'll use one rod i have in particular for an example,i have two lines i prefer on the piece one is a thick line for turning over heavy tips / offerrings up to say,,90ft,,another is a lighter wt. line (used dry/no tips)that really makes the rod `zippy' you can just lean into the forward drive all the way thru,makes the rod two different rods really,the `heavy' line you absolutly must slow down or the line will crash in a heap,even though i'm amazed at what lead.bugs hooks,,:hihi: the rod will haul with the `fat line'it's two different strokes,if the rod is underlined it's quite evident,if you're new and struggling with an overlined rod it will drive you insane,then you'll be like me:smokin:
