No you can't get an extent without 65s at backstroke. The minimum is 4 for 
Carlisle and 6 for Alnwick. For Carlisle you could have a 720 without 65s 
at backstroke which doesn't come round and then follow it with a similar 
720 or 600 for a round block of 1440 or 1320. It might be possible to do 
the same for Alnwick.

Extents with some 65's at backstroke
------------------------------------
It is impossible to get a 720 of these methods
without 65's at backstroke.
These are all the extents with the fewest number
of 65's at backstroke or no more 65's at
backstroke than the multipart extent with the
fewest.
