Glad to hear you are having good results.
As I said, I heard they would not be as good, I have not had any experience with the new units.
I would not call Overheating a quirk but more a problem and it can be a very costly one if you are the one who has to pay the bill and try to run a company with all that that includes.
Unfortunatly the Hysters here are not getting very good results and also have overheating issues and require holes and slots in the hoods to try to minimize the issue.
