I'm in your same boat. I'm going to repeat what has been said on other threads, you need to go try them out if you can. I've been stuck between the Monarch HG, Trinovid and Conquest HD. Finally went this morning to try them all out. The sales person was very willing to go outside with me so I could use them outdoors. My findings. Again, just my personal thoughts. These were all 10X42.
The Monarch HGs were my favorite. Fit me really well, super smooth focus knob, locking diopter, perfect eye relief. Just seems to mold to my face.
Trinovids were second. Felt really great, but the edges were not crisp, as in at all. Didn't mind the shorter eye relief/
I was really hoping to like the Conquest HD. Felt really solid, but just didn't fit me. Almost seemed like I couldn't get the eye cups out far enough to really feel comfortable viewing; had trouble getting a full view. Now I realize these are the "demo" set, but the focus wheel was anything but smooth.
Just glad I went and held and looked through them all. Now to find a good used pair or hope they go on sale somewhere. I hate paying full MSRP if I don't have to.
