My suggestion is go for a medium power, 12mm T4 Nag if you want a wide field eyepiece.
Between that and a 32mm TV wide field Anna finds these are her most used eyepieces, and she would never part with either.

Hi,
I am going to throw a spanner in the works and agree 100% with what xstream said in not being able to use the 9mm eyepiece all the time due to atmospheric turbulence. The 9mm eyepiece gives you 222X in your 2000mm FL scope. I think you would get infinitely more use out of of either the 11mm Nagler T6 (181X), the 10mm Pentax XW (200X) or the 10mm TV Radian(200X). FWIW I rate the 10mm Pentax XW as superior to the Nagler T6's and Radians, having used them all. The Pentax has a slightly smaller AFOV compared to the NT6 which I dont really notice anyway, but for planetary performance it is sharper, has better contrast and higher light transmission than the Nagler t6's. It also has much more eye-relief but offsetting that is the fact that it is also larger. For planetary work I also find the Pentax XW's give cooler more neutral tones than the Naglers. I also find the Radians to be warmer than the Pentax XW's. Whichever you were to choose between the 3 I have mentioned you will end up with an exceptionally good eyepiece, the differences between them all are pretty subtle but as I said having used them all I think you would fall in love with the 10mm Pentax XW.
