I'd definitely agree with others that, depending on use, it's generally better to go lighter. So lower magnification and smaller aperture. Modern lenses are generally 'brighter' than those of yester year so, again depending on use, a smaller aperture is often OK. A lower magnification is also much easier to hold steady.
Putting all that together means I went for about 8x20mm or (maximum) 8x30mm.
I'm happy for you to try my binos out if that helps.
One last thing. I'd 100% agree with others that, having decided on size and cost, you should try the whole shop's stock to view objects outside. You'll be amazed how much the sharpness across the field of view varies!
