Hi Spike...before you go forking out big bucks for the Ethos as suggested
Your Light bridge will no doubt come with a couple of EP's
I would hazard a guess and say the supplied ones will be more than suitable to start and find your way arround with.
May I suggest attending a few viewing nights, the guys/gals will be more than happy to let you take a peek through thier EP's in your scope.
This way you can get a better feel for exactly what you want and what works for you.
Cheers
