Where to begin on this one wow seriously?
As of the 08/09 season (this year in case people can't grasp that concept) the SL, Legacy, Infinity, Revolver, and Evo will only come with the never summer rocker.
TBT is on every Bataleon board so if you are scared of it then you can not ride one at all.
3 stage rocker which is what you find on K2, Rome, Capita, etc. etc. is the rocker you have to ride centered. Mervin and NEver summers you can ride it how you want its not going to matter.
If you're so scared of new technology you might as well just keep riding what you're on and be happy and content with nothing changing.
