I've had mine for about 5 years now, so I believe it's the older one(didn't know there was a new one) and so far I have tried the Cortland 444 WF 8/9-F, SA Spey/Salmon taper WF 8/9-F, the SA Steelhead taper WF-8-F, the SA Steelhead taper WF-7-F, and the Rio W/C WWF7/8/9-F, the Cortland line is the line I bought when I bought the rod and I chopped it to fish heads with , I don't mind it, but it gets kinda ugly with heavier heads, the SA lines I didn't like, but the Rio line I like, I haven't and won't chop it because I like it the way it is. I tried the SA Steelhead taper because I was told by someone knowlegable that that is the line he uses for it in the 7 weight, I didn't like it, the 8 weight I tried as I had it for one of my single handed rod, the SA Spey line I didn't like so I chopped it as well and use it for heads(still don't like it)
So this probably didn't help, other than I like the Rio the best but use the Cortland the most as I mostly fish heads this time of year.
Oh, also remember that this is coming from a guy that can't Speycast all that well and these line on this rod in the hands of a well abled Speycaster would work just fine.
I just thought I would tell you my experience with the rod and lines.
