Switched to a ZWO OAG - very bloated stars in guide camera 120MM-S - solved!

Folks,

I am thinking of switching from a giant Lumicon OAG to a ZWO one to hold my primary ZWO 1600MM-C and guiding 120MM-S cameras.

I wonder if anyone can tell me:

1. If they have tried this and does it work well? (answer - Yes)
2. Do I need any special adapters to mate the ZWO OAG to a Meade Motofocuser? (Answer yes - plus extract spacers)
3. Will I find the 120MM-S on a SCT gives near pin point stars? (answer yes - once the extra spacers are added - in the correct location)
4. Is the unit solid? (answer yes - once you tighten the Allen bolt on the Prism arm - else the guide camera wobbles badly)!

On the third point I think I have done something rather wrong. My Imaging camera gives stars the size of peas at the moment - so I think I must have the spacing way wrong (very correct) - but it's proving hard to correct what should be a simple thing to adjust.

Many thanks for any thoughts, insights,

Matthew
