koxx bloxx are known to be the best performance and make a few compounds, but if your on a budget buy some majic pads, i run them for a while nice bite, even with a deadish grind and they held. i ran some plazmos too, they not too crackin in the wet, in the dry their ace though. my heatsink blues did'nt last very long at all, i could'nt get them to bite properly, made a nice sound though. if i was you, i would go for the koxx greens/blues their the same compound but diffrent colour they mint in wet and ace in dry, you'l need a grind for these though but their mint! hope i have helped with your decision Liam...
