I have Nano XS-Pro UV filter for all my lenses. MRC has 7 or 8 coating, Nano have one more extra coating than MRC, B+W website said that the Nano coating make it easier to clean than the MRC. Those filters really easy to clean, blow hot air, wipe, all gone. MRC and Nano diff by 5-10 dollars only so just get the nano version, go mass sales there, visiontecnic very nice guy. The shops price are high ballers for filters...
