should i buy a new board?
how many days do you plan tor ride in the upcoming season?
Is there anything else you want or need that's the cost of the board?
Boards are a personal thing, I think. Everyone is different, likes different things and rides in different conditions.
Spend some time learning about different shapes and what not. Then, once you've completed your due dilligence go demo some boards. Then, you will quickly figure out what you like...For example I demoed a handful of boards and realized pretty quick what I liked and didn't like in regards to shape and stiffness.
Then, you can make a checklist and find a board(s) that satisfies your requirements and narrow it even further.
Tme consuming and expensive? Sure But buying the wrong board costs even more. Ask the shop if they will credit you back some or all of demo fee towards the purchase of a new board.
