Thanks Jase for your comments.
I am leaning towards the 2" Feathertouch SCT model with the new Motorised feathertouch system.

I do think there will be some benifit to a larger focuser but the downfall is cost plus parts to suit and most importanatly weight..there very heavy...The STL11000 is already going to add some weight to my system.
