Here's the good news. There's a model called the Stiletto Restricted and it will mount to your Salomon, and it has Re:Flex and I'm pretty sure Northwest Snowboards in Olympia carries them.
Go talk to Mike Cummins and you'll be happy with whatever you walk out with.
As far as the stomp pad goes, i'd say this:
A lot of folks don't use them and a lot of other do.
I don't find them beneficial what-so-ever. But, if you'd feel more confident with one; it's a low investment for piece of mind and you can always peel it off if you hate it.
