Definitely get the LT brackets. They are huge difference in energy transferred and saved with every step. Worth every penny. Dual risers, get them if you don't already risers on the board. The single riser works just fine. It is nice to have the two heights but it is really not that big of a deal.
Pucks, you'll need to get from Voile.
Enjoy man. Hopefully I'll be out in Utah in January. We'll have to go for a tour.
For sure man, I had single risers last year and they worked fine but Snowvols and others had the dual risers and it seemed to give a nice advantage on some of the uber steep shit around here.
Sure hope you make it out man, conditions here are SOOOOOO much better than last year, you have a free place to stay and we love to cook so we can keep it on the cheap.
