Thanks Morton.
At the moment, I use a 4 and 6 GSO for planetary as this was all I could afford when I got my scope.
From what I read, the shorter length GSO eyepieces are supposed to be pretty ordinary in fast focal lengths, so hopefully I'll see a big difference.
The Burgess eyepieces look interesting, though. Hmmm...
Pondering what to get is always more fun than the having for me.
