How flexible are they? Like R-Pro flexible?
Can you two-finger taco?
I'd say it's gummy but not R-pro floppy. It doesn't really sag much in the hand and I didn't notice it flexing hard much on good rips, enough to bother me anyway. It's got some flex to it, like those old QMS's that came after the CE runs. It's been fairly warm here recently, 60-70 degrees so I guess it won't get really soft feeling until the NC summer heat arrives, or I beat some rigidity out of it.
I like a little flex/gumminess to my discs though.
