I just started to snowboard and I plan on going a lot more. I don't think renting is worth it though might as well just get one for myself. Except I'm not sure what to get.
Size 5 womens, I think that's a 3 in mens.
I'm still getting used to things so maybe a beginner board would be best.
Also try to demo alot of different boards if you can, that helps alot with all the different styles out there. And what style of riding do you think you would like to do more of. ie.. park, all mountain and so on..
