definitely rolled up zebra mats, tiled zebra mats are dense. we train judo throws on zebra tiles (over thin carpet on a concrete slab) and when we had our local judokas come out for a seminar they just leered at our mats with a "what the fuck are you guys doing" sort of glare. despite the occasional kidney slams and injuries it worked out for the better though, in the cage our guys bounce off the mat like rubber cartoon characters.
we got breakfalls like luchadors
