Boy, that's a great question. I agonized between 8x32 and 8x42 Ultravids when I made my once in a lifetime "alpha" bino purchase. The extra few minutes of twilight viewing wasn't a big deal to me as I tested the 8x32s very late into the evening and they were fine, so that wasn't any further consideration to me. From a purely optical standpoint I did notice the larger EP was an easier, more comfortable view to me, so I bought the 42s.
After using them for a while I realized that with my style of walking hunting and mountain hiking in general, even the compact 27 oz Ultravids were too large and heavy for me. Since then I bought an 8x32 Nikon SE that I use 90% of the time.
I think with your 8x32BNs and a good 10x43 you are set. If you want one more bin I would buy a 7x36 Zen Ray ED II, that would be relatively light weight and a very easy view with almost "alpha" optics, and not very expensive.

btw, I love those little 8x32BNs, what a great package!
