I seriously doubt that H-D makes a decision to repair or replace based upon the expertise of the dealership technician. Number one, they have no clue who will be actually doing the repair. It's a monetary consideration, and the manufacturer holds the right to make the repair versus replace decision.
The initial failures were handled as a full engine exchange mainly because they wanted the engines back for complete teardown analysis, to determine the root cause of the failure. This is common in the automotive world as well as with motorcycles, whenever new models or major changes to existing models are introduced. The sad part with the 110's is that even after replacing a pile of engines, they haven't used that information to fix the problems or identify production dates of suspect engines so they could notify affected owners. They persist in taking the low road, just letting customers deal with failures as opposed to a notification/inspection/repair program to prevent failures.
If the dealership tech is conscientious and not just knocking it out as quickly as possible to make more $$$, you will probably end up with a better engine than what H-D would have sent anyway. Make sure the dealer fully documents everything, and that you get detailed copies.
