Frank built me a tantalus evo 2. It has metal under foot, and i guess carbon in front and back, with whatever else he puts in the board. I specified how tight of a trail I would be carving, weight, ablility level,etc. it is an amazing board. think is was 1700 shipped. i cant explain how that board is under my feet. once you learn how to ride it, the board gives a stability level i have never felt on any other board. I highly recommend the tantalus shape!!!!
