Just got back from the shop, long story short I ended up talking to a guy named 'Rich' who was either the manager or head tech. He recognized that it was completely their fault, didn't try to argue that at all. Immediately sent a tech to go fix it, and asked me to wait around while they remounted.
After they were done he personally brought the skis back to me, said that they were really busy right now and asked if he could call tomorrow in regards to 'making it right'. Asked specifics about the skis, where he could find information on them etc so I gave him a sheet I printed out with the name and price clearly labelled on it.
My guess is he's going to look up the specs and try to match it with a pair they have in stock. If that's the case I guess I'll go for chronic's, they seem to be closest to the MR's, 4mm skinnier at the tip and tails is all (and looks like North-east isn't going to have any powder this year anyway)
