Sub 3.5mm eyepiece for planetary/lunar

Hi all

Recently I started enjoying visual astronomy a bit more often and thought that I would like to see if a tad more planetary/lunar detail can be squizzed out of my 105mm f/6 triplet. My shortest FL eyepiece is 3.5mm Delos, which I like for its FOV (I track manually) and ease of viewing through. But it is a large eyepiece as well. My next one up is 5mm Delite and I really like how it performs with my small refractor on the planets and the moon, and it is very easy to look through.

Would a 3mm Delite be too close to 3.5mm Delos on the planets/lunar? I was also thinking perhaps 2.5mm TOE could be a good candidate as well, but not sure if I would like such short eye relief and narrow FOV with manual alt-az, and also doing 630/2.5=252x might be a bit over the top with such small aperture on the planets for a reasonably comfortable viewing. I observe without glasses.

I would appreciate any comments and advice
