You already have a very nice selection of binoculars! A lightweight 8x32, a pocket 7x21, a 8x42 for the most pleasant views and really nice for dim light and a 12x42 for longer distances!
I would be very very happy with what you have. Keep the EL 8x32! I have a NL 10x32, but would have been very happy with the EL 10x32 as well. It wasn't sold new by then anymore. I was attracted to the bigger FOV of the NL, but now I have them the large FOV is a bit overrated imo. I have the EL 10x50 as well and 115mm FOV is large enough for me (compared with the 132mm of the NL 10x32). I do not like the head rest. I bought it and sold it again.
The focuser of the NL is really smooth and the position of it is better as well. That's true!
I am a 10 power person, so the only bins I miss in your lineup is a 10 power. I miss a Habicht too, so a Habicht 10x40 would be a nice addition!
