"Saying that, I'm still on the fence re indy - I just don't think a leading party with this level of corruption is a good foundation for a new country."
Why are indy and the SNP the same thing? They're very much not. The SNP might be the vehicle which allows independence to come to fruition, but a general election would have to be called, and there's no certainty whatsoever that they would win, given that their main political purpose would have been achieved already.
I'm an indy supporter, and a bit of a floating voter outside of that issue. Don't make the mistake of giving up on a change for the generations, because you don't like a leader or party who will be gone in a decade or less.
