Havn't tried TNN's. But I have ran my phat pads on pritty much everything, harsh grinds, medium grinds, dead grind, anodized rims, smooth rims.  And you know the best of it.............Work f**king un-real on all of them   Don't think i'm gonna' be trying TNN's either, from the response i once read in a topic from the owner of plazmatic, stating that the plaz compound has never changed, now when releasing these new pads, he's stated it's the "old original compound" . Best of it is, if it isn't the old material, these pads are gonna be shit.  But seriously, how can anything compare to these:
