I have an Ibanez RG470F (6 string) which I've loaded up with d'Addario Jazz strings (EJ22) tuned to A-E-A-D-F#-B. The low string is a touch on the flappy side, but in general the guitar copes pretty well. I'm looking at going custom, though, just to make sure the low tunings are optimal, as I play quite a lot of fastish riffs low down, and the string tension could use being a bit better.
Not sure if that helps you or not :)
