A lot of well informed and experienced carvers out there helping out, thanks everyone!
It sounds like I've got a go-ahead for mounting plate bindings on an all mountain board.
The board I would be using is a Ride Theory length 159. It's extremely felxible and pretty short, I'm sure it's not the ideal board for hard boots but I really can't wait to try them out.
Once again, this seems like a really friendly community going on here, glad to be here!
Keep the polyethylene side down!
