New to the sport.
Ok so I just started snowboarding just a month ago. The group iv been going with say I have naturally good balance and am a quick learner. Thankfully learning to surf helped. But they say the board I'm using is the main think that is holding me back. We found it a goodwill and they have never seen one like it neither have I. But it is green and black and is a Nitro Diablo. The EC is 134 the heel side is 9cm and toe side is 11cm the bindings have a weird diamond pattern for the screws. Its kinda narrow and very long. Basically seems like it is made for nothing but speed. I can go straight and slightly turn extremely fast and sometimes a little to fast when someone gets in the way and since I cant turn only option is to face plant or take a bath in the snow. Im use to freestyle riding on the surf but this is more speed. I dont know much about equipment. She is a good board just wondering what type of board someone would suggest for learning or a type of board that isnt all speed.
