I've tried three sets of Mamba Premium Natural Gut and have given up. 1st set was good. 2nd set snapped while stringing, both 1/2 sets. 3rd set was very dry and brittle with half unraveling so much I couldn't string it. See pics of that last set here: http://s496.photobucket.com/albums/r...s/Mamba%20gut/
Ray was good about replacing the 2nd set that snapped while stringing, but I e-mailed him the pics of the 3rd set and have not heard anything back in about a month. Oh well, I guess you get what you pay for. Perhaps the Supra is better quality.
