I'm a real eyepiece dummy and apart from reading the odd review on the 13mm Ethos which sounds great I am really quite clueless with what to buy.
My current eyepieces are ;
Televue 1.25" 32mm
Televue 1.25" 20mm
Televue 1.25" 11mm
Hyperion 1.25" 8mm - it says modular so I think this may fit into a 2" but am unsure and am not at home as I write this
Celestron junk 1.25" 40mm - I use it to locate alignment stars before switching to a higher power eyepiece
Meade 26mm 2" - came with the lightbridge, havent used yet.
So basically, what eyepieces would you recommend if you had a 16" 1800 odd mm scope and the above eyepieces already?
Out of the above, the only one I found that is really crisp is the 32mm. All the televues i bought from bintel a year ago and were all fairly cheap.

I would go for a 6mm Televue Radian to give you 300 power, which would be high enough for all but the most excellent seeing conditions. You could use a 2x Barlow to get 600 power.
Your comment about things not being crisp could be due to:
1. Faulty eyepiece---highly unlikely with Televue
2. Faulty mirror--possible, but unlikely
3. Poor collimation--This is the most likely. With an f4.5 scope you are never going to get crisp images unless your collimation is spot on, or you are using a low power
