Atomz Seriously they were brilliant! Never failed me once, and had epic bite & hold - and wore really slowly... I've tryed Neco red's, Zoo!'s and Rock green's (on Ozzys, Andrews and Naths bikes - all on smooths), and none of htem compared to my Atomz Zoos were just terriable, Rocks were okay - good bite, okay hold, wore very quick! And Ozzy's Necos seemed good - but he had alot of problems with them (like they worked sometimes, others not atall, etc...)
