I think you should go with the custom which is made to be an all mountain board. I think you'll have more edge control and the board will feel much more comfortable for you rather than the supermodel which was really made to be a freeride board (idea for powder or off-piste riding). I have the supermodel and you really get the most out of the board and see what it can do in deep powder. You may want a board with shorter side cut so it grips the groomers better and can allow you to progress nicely in various snow conditions. Custom is an awesome board and you can hit park, groomers whatever you want on that. Good luck!
