I know the shuttle series are light and more affordable, but do you sacrifice tone? I live in the country and have no way to A/B compare. Also is there a big difference between the 12.0 and the 12.2 tone wise? For those of you who've tried both... if size, weight and money didn't matter, would you rather have a GBE series? Or are there other factors that make the shuttle more flexible? Thanks in advance.
