Hi Ernie,
I've got a couple of the Hook and Hackle fly lines. They're true to the weight designation, unlike a S.A. GPX or a Rio Grand that are 1/2 size heavy. They don't have a welded loop, but other than that, they're premium lines all the way. They float great, they're slick, they stay supple in the cold, they're durable, and the color is the best I've ever found for a fly line. It's an olive green, but unlike some other "stealthy" colored lines, this one is easier to see - but still stealthy.
If it sounds like I like these lines, it should - they're my favorite! The good price is just the icing on the cake. :-D
