if you have a hard rim, rimjam greens are absoloutely immense! the squeak is so loud and the hold is so good it wont budge if you try, but there crap on Cheese rims because the grinds arent sharp enough, JT! i never said you were made of money and i didnt say buy Coust pads right this minute! all im saying is make sure the next time you change brake pads if your still using a Cheese rim get those, there the only pads that will work good on it ;) everyone will suggest other pads like, koxx yellow's, plazzies etc and fair enough they do work alright, but if you want a immense brake get the coust pads and grind you try-all rim up :)
Also if you download Biff's video you'll hear his brake is quite good, thats because he's using plazmatic crm's (correct me if im wrong biff) which are a similar compound to the coust pads. also if you want more info PM 'Lee_Buchanan' i beleive lee was in the same situation as you then he tried coust pads and never looked back (Whilst using his Try-All rim anyway) so dont start getting bitchy, im only trying to help (Y)
