Surfing Waves

Hi,
I am going to buy a new Walden magic model...
I wonder what will be the difference between regular PU or FutureFlex.
Today I am riding a PU longboard (also walden magic) and like it a lot.
Would appreciate your opinion and replies.
Thanks!

A bit late, sorry usually the best way is to go to the Walden site ( in this case the Global Surf Industries site) and they have the tech specs there, as to how they ride, only a Walden rider knows.
I don't so I don't! Just a courtesy reply really
