Re: 6 or 7
for ibanez, their 7 string necks are really easy to get used to. I have large palms but short fingers (stop trying to imagine) and I am Asian, but I have no issues switching from my S520EX's Super Wizard neck (bloody thin, flat, fast neck) to the RG7621's Super Wizard 7.
Well, okay, the super wizard 7 neck is thinner than the current offering on the 7321 but still!
I guess the more important question is really, are you willing to do something different?
