Been thinking about it at work, and I think the Pentax 14mm might be the better choice, but it's all guess work for me.
Fortunately I'm a great procrastinator, so I won't be rushing into anything! The 22mm Pan sounds very nice too. I'm making a list, and I'll narrow it down bit by bit.
Thanks for everybody's help, and anyone else with any ideas, please feel free to leave your suggestions. I will take notice!
Cheers,

I own a full set of UO HD orthos and also 4 Pentax XW's. I have also used most of the televue eyepieces.
The 10mm Pentax XW is 1 of the best eyepieces I have ever used but I don't think its right for your scope, as the 235X magnification it gives, will not hold up all that often due to atmospheric turbulence.
With the long focal length and narrow FOV of the C9.25 OTA (which IMO, is the best small SCT OTA) I think you would be better off going with either the 24mm or 22mm TV Panoptic. The 22mm is probably a slightly better eyepiece than the 24mm but its more expensive and somewhat larger with a 1.25"/2" dual fit barrel. The 14mm Pentax XW shows minor field curvature in faster scopes but works very well in an F10 SCT and I think this is an excellent medium/medium high power option. I would then get a good 2X barlow to use for your planetary viewing. Your better off with a couple of good eyepieces and a high grade barlow than a lot of lesser eyepieces. The UO HD orthos are very good planetary eyepieces but in a SCT they give a very narrow FOV combined with short eye-relief.
At some point in the future I think you also need to consider a good quality low power/wide field eyepiece like the 35mm TV Panoptic.
I wouldn't waste my time using the barlow you have with a Panoptic or Pentax XW, the quality of the sytem is only as good as the weakest link. If your going to use high grade eyepieces you need a high grade barlow.
