Hi Martin,
I dont have an lx200 (just couldnt stretch the budget that far)... but i do have an LX90 set up on a super wedge.
Firstly, have you had a look at:

There is an excellent guide on setting up polar alignment in the southern hemisphere.. and Chris uses an LX200. I used this guide and it was the answer to almost all of my problems.
When you get your scope close (10 degrees is a lot though), then drift alignment is the way to go for sure. Its all explained easily and clearly in the above article.
