The gama is a step above yorur typical mono in terms of stretch and sensitivity. I still like the flourocarbon for feel. Have you tried Seaguar Carbon pro, or even better is the Seaguar InvisX (much less stiff than standard Flouro's). I have tried all kinds of flouro's and the InvisX is the best I have used. It is much more abbrasion resistant than mosts, but you still need to check.

I can say the Gamma co-polymer is the strongest line I have ever used, and it lasts forever.
