Dear X metal experts here it goes: I've planned to get a piggy bank to finally one day get a pair of mars craters. I'll start to fill it as soon as I get out of unemployment that is. Anyway since I haven't seen any other metals in person than R1s I'd like to get some info to move bad thoughts out of back of my head. All I see on O forum is that juliets need a tune up from time to time. My question is do mars also need those tune ups since from what I see people don't grumble on them that much. I'm curious if juliets are more prone to the wiggling effect or people just don't wear mars that often and that is why they seem to be free of the wiggling effect? Next question is how often should I expect to make the tune ups if using youe frame daily? I've got quite a slim head, no watermellon or anything. Aside of julies and mars I also love pennys and I assume that because of the spring hiinges (which I believe are something similar to madman's but I can be mistaken) they should be the least prone of the three mentioned frames? Any thoughts would be highly appreciated. First guys on top of my head that could help me out @kronin323 @Migs the Scientist @VolcanOG I know you guys rock all those frames.
