I went from bz double platinum to science ms1.
Bz lasted almost a year before it had 3 creases in the slick and a fat elbow crease... the rocker also disappeared and i was riding a banana for a few months. But the board was lank fast, really flew was a little stiff though.
The science is bout 3 months old now not as fast as the bz but i get lots of projection. There a little bit of a elbow crease forming now... still goes lekker though. Lot softer than the bz just wish it was as fast.
Just for the record, bz was 42 and science is 42.25.
I am bout 1.89m tall and weigh round 68kgs.
Ride your friends boards till you find one you like

If i found another double platinum when i was looking for a new board i would have bought it. The new hubb looks way too thick o.O
