You mentioned using 3rd gear around town as an option. I my opinion it is something of a must do to insure the transmission has a long life.
In my experience 700r4's have a tendency to constantly shift in and out of OD when your driving in the 35 to 40 MPH range depending on throttle position. This continuous shifting causes heat to build up in transmission.
I don't shift mine into OD under 45 MPH and then only if I will stay above 45 for several miles.
