Gabe,
I
tried hard booting for the first time last year at SES. If you can make it to one of the Expression Sessions, I highly recommend it. The people are awesome; so friendly and helpful that you can't help but improve and have fun doing it.
The set up I started on was a Burton Coil 173 with fairly soft old Burton bindings and a new pair of LeMans boots. In terms of binding angles, I just did what the BOL articles suggested and set them as low as possible without any overhang. Basically that meant 50/45. Considering I ride 18/6 on my soft boot setup, it was a bit trippy at first. Just go slow for starters until you start to feel the rythym.
Sean Cassidy suggested riding in Walk Mode to get used to the stiffness and I found that helped. Then once I stared to feel comfortable with the set up I played around with the foward lean, but basically I now ride 3 & 3, which is the middle setting, locked on both boots. That is, unless it is cruddy snow (which is most of the time in Australia) and then I just go back to walk mode.
At SES I demo'ed the Donek Axis and the Prior 4WD. Both awesome boards. The extra width certainly helps in the transition from soft to hard boots. I don't recommend going to a narrower board too early because it will require a much more aggressive angle on your bindings which is tough to get used to. I tried a Donek Freecarve and just couldn't quite get it at the time (though hoping to graduate this year).
Other than that, all I can suggest is to just ride and ride and eventually it all clicks and you don't even realise it.
Good luck.
Cheers
Dan
