I recommend starting with 15/-12. I've ridden between 18/-15 to 12/-9 which I'm at now. There are trade offs as you increase your angles. Too duck and you start to lose edge precision, to straight and you reduce your ability to open up. It's really personal preference. Pick something and commit to riding it for a long time. It takes some time to get used to new angles, and you really don't know which is best for you until you give yourself sufficient time to trully adapt.Thanks for the quick reply
Also what do you recommend for the angles of the binding?
