Eyepiece for an f4 reflector

I just recieved my new Orion Skyview Deluxe 8 EQ Newt and was wondering if anyone has any recomendations on eyepieces for this scope? I would like one eyepiece for the best close up views possible of the planets, as well as a good choice for deep sky work. This scope is relatively fast at 800mm f4 and I understand it can be difficult to shop for. I have the included 25mm and 9mm plossls as well as a 3.7mm Orion Epic ED-2, which gives dissapointing performance. Does anyone have this scope and any recomendations?
