I have looked through so many Ep's and looking for a high power can be a puzzle.
But with your Dob you would like wide field at high power. So as John has said the Pentax's are super. Also the Tele Vue Radians are nice as well as Naglers. Ortho's are very good and Plossll's are great with smaller fields.
With your new Barlow as i have you then get larger Images scales so 14 mm down to 7 mm work well.
For me I really like the Meade 8.8 mm UWA Barlowed, when seeing is good it is really nice and sharp. Still with a big field for a 4.4 mm
Good hunting.
