Any Ultex Jazz III fans here?

Surprised Joe hasn't given these a try. Or maybe he has, I dunno! I personally really like them and prefer the tone over the red/black Jazz IIIs. They're a bit stiffer and smoother over the strings, much less flexible meaning they don't "drag" plus I think they sound a bit bigger. Quicker attack but overall a bigger tone I feel.

Anyone here into them?
