Good looking tree!
Not to open and old topic again here, but which is it? Do you want to pinch new shoots or leave it be? Or, worded another way- Are you trying to heal those big scars or maintain a perfectly ramified tree?
Looks to me like you have a tree that needs to grow out, move some wood to cover some scars, chop back, then Let it grow again... If you pinch the new shoots, you will keep those coveted short internodes because the tree just won't grow a whole bunch, won't develop a lot of vigor and it certainly will not fill in those big holes for you very fast...
Regardless of what you do, you have a nice tree and you MIGHT wind up with two pretty good trees if you layer it- but you run the risk of killing the top and bottom if you mess it up... Or certainly risk killing the top at the very least... Why risk that for the potential reward of two trees that will take a decade to become something when you have a tree that is pretty damn nice right now!?? 100% disagree with the air layer recommendation. I am glad you seem to not be considering it! The most drastic move is not always the best move. Sometimes you just need to let a nice tree be what it is going to be!
