actually UHF was a tradename owned by the Soapshoe brand for the plastic/grindplates, as far as i know. Im not sure it was a company as such.

Anyway, in my experience;

UHF Original; These were the first plates i had, and i learnt to frontside, UFO, and farfenugen on them without too many problems. However, as Antho said, the plates had no moulding as such and were just arch shaped plastic. The lack of any shaping on the outer edges of the plates meant that if you were doing anything like a royale or farfenugen or ufo etc, which requires you to grind on the edges, there was virtually no natural lock on. Fortunatly (and unfortunatly) the plastic wasnt very durable so grooves formed pretty quickly and solved the problem, but at the same time meant that the plates wore away very quickly and needed replacing (especially if they were used on anything other than metal handrails)

BBKs; These solved most of the issues associated with the UHF originals. There's good lock on for the basic frontsides as well as tricks where you grind on the edges, because of the new moulding. Also, the plastic was far more durable so grooves that could ruin the already good shape of the plate wouldnt form easily, and the plates didnt need replacing as often.

Cool......i want yellow BBKs.... :)

.....honestly....get a few spare BBKS if ur gonna get replacable plate shoes first....that way u wont have to worry about destroying a pair of plates with the fear of "OMG I DUN HAVE ANY SPARES" By the way, they're not that exprensive

what size are you?.....my AIM is AnthoFlex if you wanna talk more

I know but a few colors wouldnt kill you....not to mention id ur gonna do concrete ledges, that crap will kill ur plates faster

True... but where get curb busters?

uhf sorry
bout that
