I have been out of the wakeboarding scene long enough to quickly lose track of the latest greatest equipment. The only advice I can offer from someone who has been injured numerous times and watched pretty much everyone I rode with get injured is to get good bindings. You want to be locked into the board as much as possible. On a serious header/digger you won't even feel the board go, but a single binding release leaves you open for serious knee damage. Bindings must fit properly, and have good hold. There is no one size fits all that won't leave you open for broken ankles and torn up knees.
The board is up to individual taste. One person likes a slippery board, and another like a board that rides like it is on rails. Myself I like something right in between. With it being on the shorter side and light for shifty's and spinning.
I wish I could still wakeboard
I miss my Nautique and all the good times out riding the river system with friends.
