Super sorry about the metal. Sucks - but is not unsurmountable. I'm 46 and my life goal is to be the oldest dude rockin' it! BTW - my left rib-cage has ripped away from my sternum - looks like you might imagine. That was a tree while racing first run at Lost Trail - MT on a killer powder day. Hurt twice if you catch my drift.
Anyway... I hear you about the plates and angles. Without knowing much about your situation, I'd imagine that angling forward would be helpful for you - unless you are fighting it. Sometimes a guy can feel hesitant in such an aggressive stanch. My advice.. Get Agressive. Don't be stupid, but believe in yourself, your board and your ability to carve it up, Bro. Best of luck - BTW.
Oh... and I have a pair of SnowPros that are pretty stiff, but have great options for canting which I'd also guess might help you.
