What you show is exactly the same issue I am facing. Right down to those little burnt tips an the newest growth. Kym has had Lindsay Bebb state this is a virus(don't know which) after viewing what is going on with hers and she has viewed these leaves (on the linked thread) and believes it is the same as her's. Yet Don and Ray from given descriptions of burnt deformed leaves(that return to normal through the season) state this is exactly the symptoms of Thrips. They and the Internet say by the time you see it the damage has already been done so there is little you can do but wait. You could defoliate and wait for a fresh set of healthy leaves if you are keen which Don suggested but after the fact this is probably nothing to do with the health of the tree only cosmetical like wind burnt leaves you can leave them on or remove them. The later looks better but uses more energy as the tree can still use a damaged leaf.
It has been mentioned that it can not be ruled out there is more than one thing going on here but this sure looks like thrips compared to the pictures and description on the Internet and two very capable nurserymen also believe so.
I am unsure if the neighbours tree was going to cause any further damage for the year but I feel much better that it is gone.(see other thread)
I am confident I will see an improvement in mine very soon.
I will be taking a sample for Tony Bebb to look at on the weekend to get a 5th opinion

I have had Oak hawthorn robina tallow trident and probably a couple of others affected by this.
Hornbeam elm cherry and plenty of others have not been affected. Don suggested this may have alot to do with the time of bud burst as the thrips have a window that is the attack period and if they have not leafed out they are not damaged. I also found that the ones in the shade house where not affected. Don also believed this had more to do again with these ones budding out later after the threat had past. I thought it was because thrips can be carried by the wind and the shade house was more protected.
It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
