If you are looking for a good mount for a C11, then a G11 is an excellent choice....., provided you are prepared to learn it in detail. The mount has many excellent features but needs periodic adjustment and that includes the software. I had an eq 6 and upgraded to G11. The EQ 8 may be a different beast but there were serrious issues with EQ 6 that required considerable physical reworking to fix including the alignment setup. G11's are precision made on every level and beautiful to look at.
Gemini II is new and still has some issues but will pay back with time. Until recently, G11 was considered a superior mount and I still think it is. I recently sold mine but missed it so much... I just bought it back! Finish is exceptional and performance is legendary. They are also obscenely cheap at the moment and can be picked up for around 3k with GII
I just had a look at this:

Looks tacky compared to a G11. IMO
