High power eyepieces for TOA-130

For those that have a TOA-130, what are some good choices for higher power eyepieces?
Say 150x to 300x. I don't wear glasses. I have a 9mm Nagler which gives me about 110x. Please no eyepiece wars, just looking for what others may be using.

Thanks

3.5mm Nagler, 7mm Nagler, 11mm Nagler all seem to do a fine job in my TOA-130. Seeing conditions need to be good enough to support the 3.5mm or similar focal length eyepieces, of course.
