So I've finally tried gut (BDE Rallye in a hybrid w/Klip ultrafibre syn gut), and you dudes aren't kidding - this stuff is lively! I probably strung it too low, too. And this coming from NRG. Other discoveries: 1) Gut can, in fact, survive being strung with a Klippermate 2) Gut is indeed super finicky. Look at it funny and it'll kink on you. Might also be too soft a string for my Tour 10 mids.
