I can put the Long Delta on my loop easily if I put the mid spey on ther it is tight. But works.
Loop's lines are neat, only thing that bugs me is stripping in all that line in the winter to enable the shooting of it. Cold hands and fingers buddy.
I chopped up a WC once it worked nicely with 15' tips. All in all you can't beat the a-flo polys for getting deep fast.
