Congrats, its not that easy to get that many but once again all I can say is:
Been there done that TWICE. My zon has fully sutied 3/20/20 with a alternate suit of 3/20/5 to get heavy run/walk or heavy life. Also my barbarian had a full suit of 3/20/20 at the saem time my zon did so thats 78x 3/20/20 not to mention I had like 10 left laying around for trading. Eventually I sold off the entire barb suit and got better charms (the ones im about to explain) and build my V/T.

Actually going fully 3/20/20 is not the best charm set up. Using what I have is much better. 10/75+/40 destroy a 3/20/20 set up. Use 10 of those (valued about 8 runes a piece) then 9x 3/20/20 and youll have a good 4,000+ more AR and 500+ more damage. You may lack 400ish life but 4k AR and 500+ damage definatly beat it not to mention your a barb, its very easy to get life.
