Hello, I just started snowboarding a few weeks ago and really enjoy it, but I'm a little confused about what size snowboard I'm supposed to be using. I've been renting the equipment up to this point, and the first four or so times that I went boarding they gave me a medium board, which is a 152 in length. I've been getting better, making linked turns and starting to carve, etc.. But today when I went, the guy at the rental place said I should be using a 155 board length, so that's what I got. I found it really hard to turn, and kept falling down
I'm guessing I just need to re-learn turns, getting the new feel for the longer board and I'll be all right with a 155, maybe. But I don't know if I'm SUPPOSED to be using a 155.
I'm about 5'11" without boots on, and weigh 170 lbs.
Please help a confused newbie decide what board to use
P.S. Please don't just say "use whatever feels good!" Because, at this point, I'm still falling a lot and nothing feels good
