When i bought my Mini lat summer, I wasn't used to to using .13's. They felt thick and stiff to me. I tried every type of string - from different manufacturers. Probably 20 different kinds of strings - my wife thought I was nuts! 10's, 11's, 12's... Sunbeams, Retro, DR Rare, HD Lights, etc etc.. All of these strings caused and incredible amount Fret buzz. I even adjusted the truss rod, (all the way!) and shimmed the saddle. Couldn't get rid of the buzz. So I relented, and put a new set of Elixir PB 13's on. I also replaced the saddle with a Taylor Micarta Saddle... Now I'm used to the .13's, and I love of the feel of it now -- go figure. No more fret buzz either!
