Trial and error for me also.
I have found my preference is for eyepieces with around 20mm eye relief.

I particularly like the early Japanese Plossl ( Volcano Tops ) ... good glass and very nice coatings...but you need to find ones in very good condition to be worth while having.

Orion Orthoscopic, Vixen LV's and LVW's, early Meade and Celestron smooth side Plossl are my choice most times ... all give very crisp and sharp views ... the fov is smaller tho'.

RKE 28mm ( Edmund Optics ) are amazing for that ' port hole ' experience.

For Wide Views ...I have a couple of grenades .... 40mm Super Wide Angle Meade Smooth Side, and a Vixen 30mm LV ... both of which are 2" Barrel.

I do have a couple of ' modern day ' eyepieces .. Delos 10mm and a 14mm Morpheus.... both have huge glass and excellent eye relief and not to forget 2 x TV25mm Plossl.

For Zoom...my pick is the Vixen LV or the underrated Orion Zoom Eyepieces.

All my eyepieces get used between my Scopes one way or the other.

My favourite setup is using Baader Binos and the pair of TV25mm....terrific for general viewing and really comfortable.

For Planetary viewing, I only use my 339 f/15 ....spectacular on Saturn and Jupiter using 10mm and 14mm Oculars.

If I want to push the Scope , I'll use a Barlow.
