That's kind of a general question there... but...

Boards: I lean to freeriding; I like chutes, gullies, steeps, trees, and (of course) powder. I learned on a Salomon Forecast 156, then got a Salomon Mandate 161, and now I mainly ride two boards, a Winterstick ST 162 and Salomon Burner 167. Out of the boards I've tried, I have to say that I've liked the Salomon, Nidecker, Lib Tech, and Winterstick boards the best. But there's lots of good stuff out there.

Bindings: Nidecker Carbon 900, Nidecker Pro 800 (got these at Sports Basement), and Burton Mission. The Nideckers have a great smooth, responsive feel. The Burtons are lightweight and have a good ride, but don't seem to fit my boots as well, no matter how much I adjust them. I also hate that stupid clip on the highback of the Burtons.

Boots: Northwave Kevin Jones and Nidecker Versus (another one from Sports Basement). The Northwaves are stiff, heavy, and keep the feet warm and dry. For some reason, the Nideckers get really damp in warm spring conditions, but I generally prefer them when the conditions are halfway normal.

Something you ought to know if your job involves selling this stuff is that boot choice is the most important element of a first snowboard setup. Basically, uncomfortable boots = ouch = not much fun = why would anyone in their right mind want to learn this sport?

As far as clothing goes, the usual nylon outer layer. Mid-layer has fleece pants and wool sweater. Most people go for a fleece top, but that's too hot for me. Wool (preferred) or Thorlo socks. Mittens unless it's spring, when I just wear some light windproof/waterproof gloves.

Last but not least, I always wear a helmet. I've never been sorry about that...
