You already have a great all mountain board that looks like it suits your riding and location well. I think you just have end of season need to buy something syndrome.
Unless you have a specific reason and something you are not getting from the Turbo Dream I wouldn't bother.
Rider is 95% the board is maybe 5% if not less.
If you do buy a board buy one that has a different feel and different strengths. Thats building a quiver rather than just spending money. Reps love to sell stuff, thats how they earn their money.
Maybe get some bindings or boots or wear, something you actually need to upgrade.
