Normally you'd want something pretty stiff for a freeride/all mountain board, but if you've only been snowboarding 10 times you might want to look into something a little bit softer. A softer freeride board or one geared more toward being a true do-it-all board will probably serve you well as you work on developing your skills in all areas. In other words, you probably don't need an ultra specific board to get better. For example, if someone has been snowboarding 10 years and mostly freeriding, they aren't going to want a medium stiffness board, do-it-all board for freeriding, because they are capable of outperforming the board. I'd suggest something right in the middle because you probably won't be able to out-perform it, and it will allow you to work on both freeride and freestyle skills.
