I've ridden the new 2014 Reflex. I love the outline and shape. The round tip and tail are loose but the board still tracks and holds edge well. Its a great board for the park or behind the boat. Its got great consistent pop and landings. Like all the slingshot boards its built like a tank and can withstand tons of abuse.
Going from the Marek to a slingshot reflex its going to be like a different sport. The flex is a so much fun. Gotta try it!
