I have an Airflo Cleartip Tropical short coming in 8 wt. I plan to fish it on an 8 wt TCX, but I have other 8s to try it on also. Airflo gives a head wt of 400 grains but I think that is for the entire 51' head. I spent a short time with one of these lines on a 9 wt (TFO Mangrove)last year and it impressed me enough that I wanted to try it on my 8 wt. As part of the same order, I also have a 5 wt Amplitude smooth bone fish on the way. I am going to try it on the new X in a few weeks. I will post my impressions here after I fish both lines.
