So far the following lines have been recommended both here and in an Icelandic BB as memory free or near memory free lines:

Rio Selective Trout II and Outbound
Snowbee XS
Wulff triangle taper
3M Scientific Anglers XPS, Trout and Sharkskin
Cabela's Prestige
Jim Teeny Long Shot
LOOP Opti-Stream and Stillwater
Cortland 555
Airflo (newest type)

A few of these lines are not available locally but I can order them online. There is obviously a jungle out there but there seem to be a few lines that have little or no memory. This is going to be a headache for me!

What about lines with interchangable tips? I have one from Airflo 9 wt used on a two handed rod which is ok but it just does not feel right on a one handed rod. I am not sure that I would like such line on a lets say 4 wt one handed rod. I did see a promising line from Rio Coldwater VersiTip http://www.rioproducts.com/product.php?recKey=14

What do you guys think, is this line usable on a light weight one handed rod?
