I have 3 different 3wts with different lines on all. I have two of the Three Forks, one with the 444 clasic peach DT3 and one with the cheapo line that came in the package. I like the 444, but honestly don't see lots of differences between them except that the cheapo line seems to float a little better. I also have a Cabelas LST 3wt with the GPX that came with it and like that combo a lot and can cast it much better than the others. I haven't tried switching the lines around to see if it makes a difference. I use the Three Forks with the 444 peach mostly in ponds for bluegills and bass and some catfish and it does fine. I use the LST for trout, throwing every thing from a #8 woolyburger to #12 Cracklebacks, to #22 cream midges and lots in between and it handles them all well. I guess it would be best to buy what you want and get used to it and make it fit your style rather than buying several $60 dollar lines and switching around.
