Suggestions on eyepieces for C11

[mal-j]

Hi, 

I've recently acquired a Celeston C11 sct and am wondering what others might think are good combinations of eyepieces to use. I have a selection of 1 1/4" eyepieces but intend to use 2" ones with or without a 2" Barlow for planetary viewing or deep sky. I'm thinking also that the 2" eyepieces might be more useful for deep sky use than planetary.  I already have a 20mm 100 degree ES 2" eyepiece and the 2" Barlow,  so any ideas about other eyepieces to get will be much appreciated. I'm up for getting a range of cheaper ones or just one or two more expensive ones if that would be better. I'm replacing the visual back on the ota a with a Baader 2" ClickLock Adapter for 3.25" SCTs in order to get the most light through. 

Thanks,
