Re: advice on a board/size/style for newb
Board should be over 140. Buy something from last years stock, you'll get it 30-50% off from new. Boots should be whatever is most comfortable. Spend money on boots ahead of the board. When you first start off set the boots a comfortable distance apart on the board and for your first runs set the angle of the boots up like you would on the snowboard. After a while you'll want to set them more equal in terms of angle. Most entry level boards are continuous rocker which means they have a consistent curve on the bottom. A three stage rocker means there is a bend in the tip and tail of the board, in addition to the curve. That style can help you jump higher but can be more work while riding.
That will give you something to start with. I'm your size, and I am no where near as good as my 12 or my 14 year old kids. I got a flex style board because the landings are softer and closed toe boots from Slingshot. The board and boots are better than I am but they are easy to ride just the same.
