If you ask 10 list members you will get 12 opinions on how and when to use 
the overdrive.  Here's mine:

Use it as if it were another gear (which is what it is).  If you are 
loafing along and want to upshift, hit the overdrive.  The O/D is really nice 
in 
traffic where you are speeding up and slowing down.  20 to 50 MPH is easily 
accommodated with 3rd and 3rd O/D.  No clutching required.  3rd O/D is 
especially nice when entering a highway.  3rd will get you up to 50 and the 
switch 
to O/D will run you on up to 70 where it is safe to merge into traffic.

You have the A-type which has an accumulator which makes the shift into O/D 
a bit sudden.  I like to dip the clutch pedal a bit when hitting the switch 
to lessen the impact on the drive train.  Others rather like the "kick in 
the a$$" feel when engaging the overdrive.  My TR6 has the J-type and doesn't 
have that issue.  I engage it whenever I feel like it whether it is high 
revs, low revs, full throttle or no throttle or anywhere in-between.

Play with it and see what you like.  You will really have to work at it to 
break it.
