Out with the old... In with the new... I plan on doing a shackle flip, maybe the home made variety. I'd like to get rid of that block. Is there anything I can do to my new 52's to ensure that they flex well? Flip the overload? They have one more leaf than my old ones, does this matter much? I was wondering if I could take our a leaf or something. Anyone else ever messed with them? Then there's the shackle flip. I was looking at the tech article and it seems simple enough, but I haven't seen many people sporting the home made version. Hows the articulation and shackle angle, anyone ever have any problems?
