I prefer Art Blades but only if they are right as far as the art and if it just ties in well with the play field. Just being picky with that regard.
As far as mirrors they seem to go good with music themes. I do have them on my MB but I'm ready to replace with art blades I picked
up from pinsider, SILLYOLDELF. Picked up a set for LOTR as well. Really awesome looking on both. I might swap out the mirrors on the MB and install on my TOM. I think they would tie in well on that machine. Oh, My SS has mirrors which look really good on this pin. I do like the blades that are mirrors and have art on them as well. Thought about doing my MET in these.
