the name brand dmc technics mats are good. thats what i use with the plastic sheets that come with the m3ds under em. they're thin and compressed so they hold up well. the generic ones lose their shape too easy.
i'm a little younger than most of you guys. i like mostly '90s ish more so in the beginning of the decade and decreasing as it goes on. i really need to brush up on my '80s stuff tho. i'm lackin a lot of knowledge.
