Hi Peter, I probably should update my signature  , I have a Central DS 600D cooled camera now and am very happy with it as I get limited time under the skies and don't think I would get the most of a mono camera with the time I have.
I appreciate your honesty in the mechanical side of things, if you can elaborate a bit I would be grateful. The driver for wanting bigger was that I have an RC8 at the moment and from what I read a 12" scope will be able to better resolve the finer details (something I feel lacking under the SEQ skies with a smaller scope). I would opt ofr an RC12 but cost is a bit prohibitive after the EQ8 purchase 
WRT collimation tools, I have these but you are quite correct in the change over needing other items such as coma correctors and additional plates and maybe even an OAG
Having said that my first experience with that was woeful LOL so would like to steer clear of OAG's as long as possible. I have read that Newts are more prone to flexing so perhaps that would be the mechanical issues you refer to????
Again that's for the advice, it will definitely weigh in to the decision making process.

My experience with newts is that without an OAG it is very hard to eliminate flexture for longer subs. This depends on how long you want to go of course, but currently I shoot 30 minutes narrowband with good results. My GSO newt had huge issues holding collimation as it changed orientation which I put down to the steel tube, the sub standard mirror cell, and flimsy spider system. As far as a larger scope recording more details, I would be very cautious. I'm not sure that this will be the case. As far as I am aware, more aperture will resolve stars better, but as far as detail im not so sure.
I think that the local seeing will play a greater role as well as the sampling of your setup, which may well be better for deconvolution with the RC8.
