the raging carbide is the overseas release and that particle is the us version. i had been told that they were the same just the name was different.

There has been a Fuze Eliminator for overseas which had "Carbide" on it instead of ProActive, but with the same colors. Seems to be a similar marketing pattern behind this

Brunswick's particle is made from carbide, like very tiny glass shreds which are baked into the coverstock and acting like spikes. In fact, that's the basis for diamonds and probably the reason why Lanemasters call their particle "Diamond".

On many international Brunswick balls you will find "Cardide" instead of "ProActive", which has now been changed to "Particle". There has also been an international Fuze Eliminator with the Carbide label.
