I'm all for maybe doing any large reductions you think are best, then leaving till next Spring.
It is SO MUCH easier for others to say "leave it, patience" etc.. all that boring advise, cos its not our tree and we aren't the ones itching to work on it! Don't you hate that?!
But yeah, I think you know by now it is a great tree so the patience is worth while. Also, only reason I say maybe reduce anything is cos it'd be painful to waste a year of potential healing and scarring, if you make reductions on large branches.
At the same time, in the grand scheme of things, not a big deal.
