I posted this info in a post about the WCR boots. Intuition has redone their entire line and they have discontinued the Pro Tongue liners. For those that loved this liner (myself included) this is disappointing news. But, the replacement may work for many. Its called the Downhill Tongue High Density 9mm liner. According to Diana this is a little lower volume liner than the pro Tongue was, but also quite stiff and with a decent amount of bulk to take up some space in the shell. The WCR 93 last line has a very thin heel pocket. These have a shot of working with those shells (might have to grind out the heel pocket more and possibly may need to bake and mold them more than once as they lose volume on each baking).
Here is the link to the new liner:
