i got standard technics ones, work a treat once you polish your platter,
or get those butter rugs what ever they call them now of days to stick between your slipmat and platter for super slidyness

i like the soft white material type, looks a bit like tough cotton wool ...slippy enough for cutting , jugglin etc but no too slippy...

table clothes - mix edition (the scratch version can be too slippy for normal mixing...

I'm rocking the DJ shadow versions...

They are the same type of slipmat that came with the turnablelab edition of the shibuya breaks

Check out the Dr. Suzuki Mix Edition...

They're not nearly as thin as the Butter Rugs, they don't cling to the platter due to static, and they give the right amount of slip... def dope slipmats...
