Hi Ian.
I have the 9.25 XLT OTA on EQ6 with SynScan (Goto) and it's a great outfit.
Don't know a great deal about the CPC range but imagine the fork mount presents a challenge as far as long exposures and field rotation is concerned
I'm sure it would be fine on planets, but DSO might be trickier.
Also, how does it go pointing up at zenith? How's the clearance with the mount?
Sorry I can't be of more help.
