Is this snowboard too wide for me?
A little background: I've snowboarded maybe 4 times before . Last season was my first time going with friends. I went twice and felt myself improve a lot more than before when I would just go with my sister (because my friends are good and I was forced to keep up). I also skateboarded for a few years until about 4 years ago so I assume that also helped a lot with balance and confidence.
Now I am 20 years old and have grown to enjoy the sport and look to get on the mountain more often with friends. I decided to buy a setup (board and bindings) due to good deals on cybermonday at evo.com. After looking around once again I am now unsure if I made the right purchase due to concern with sizing (wide board). I am 5'10. 165 lbs. I also measured my foot with a ruler: 27cm/270mm.
2014 Rome Tour 158W - 263mm waist width
2014 Burton Mission Bindings - Medium
Is this board a decent size for me? Is it too wide? Also, any suggestions on snowboard boots?
