Replying to CAST touring

Anyone know the best way to contact these guys. I’ve tried email and insta.
Or anyone close to CAST know if they are developing a STH 16 compatible system?

Wondering whether or not I should hold out a year. (Not a pivot fan at all+ I have a stock of sth2 16s so don’t want new bindings).

And to people using the system already- how stoked are you? I’ve been using the kingpin and I’m really not a fan of descending with the low tech toe. I’m used to running my dins at 12 and I’ve had so many release issues I find myself locking the toes for the down. Which I’d rather not do for my old knees.
