well i had an old pair of juliets. no serial # think could be 4th gen. not even sure. they were very goosey in the nose bridge area. i just got them back from the xman and it's like i got a new pair. really the thing is so tight i don't even need temple shocks. got em anyway but just saying it's awesome.also he changed em from the silvery (polished or plasma not sure) to the xmetal. couldn't be happier. thank you x-man!! earlier last month i picked up my 1st pair of XX 24K. and about a month before that i got my 1st pair of pennys.
