My fear of finding sigma octantis from the suburbs, polar aligning in general etc held me back, so I continued on in Alt/Az mode for far too long. I even considered a field de-rotator rather than using my wedge.
I finally decided to give the wedge a shot, and much to my surprise, have never looked back. I agree that damping times on a wedge could be much better. Given that you're in an obsie, factors like breezes etc should be less of a problem. If you keep your cable management spot on, you can minimise any problems there too.
I also think that the wedge, straight out of the box, is far from being smooth. I greased mine up and it made a huge difference. There are a few pages out there written by people who have done various things to their meade ultrawedges to improve their performance.
I say - give it a go. What have you got to lose? Ask a friend to help you get your scope mounted up on the wedge. A 12" is too heavy for one person to mount comfortably.
I used the plum bob at solar noon method to mark true south on my observing platform and it was spot on. If I wheel my 10" LX200GPS out and align it on my North South line, I get Sigma Octantis in the finder every single time. Even in the suburbs, you'll very quickly get the hang of finding sigma. It's not hard at all.
I used these two links as my How To for polar aligning on a wedge. It made the whole process simple and straight forward.
Link 1
Link 2
Take a read of both links - they're good value.

Thanks a million floyd_2 (Dean). You have hit the bullseye............and I can feel a wedging session coming on! Yes, there a no wind problems in my Sirius dome, which by the way, I consider to be the Bees Knees. Cable management with an electrically operated go-to is a problem even without one or two cameras on board. I shall give some thought to that one.
I like the idea of the noon plumb bob. I haven't checked out those two articles yet. If it is not covered, can you give me the good oil please?
Many thanks again.
Chunky
ps It is so long since I last went on IIS that I have forgotten why I have 'Cauliflower Cheese' under my nom de plume. What is it in aid of?
