almat,
These guys all make very valid arguments, like a lot of us on this forum, several of us have quite a few rifles and shoot the many different disciplines, with different rifles
. I know a couple that only have one rifle, one sight etc. beware of these guys, they spent the money on quality equipment and they shoot it well, their opinions are strong with justification.
Myself, I change guns, build something new, buy parts and change everything up before every shoot it seems, there is very little consistency in my world of shooting - but I have a lot of fun! I have a few of Shaver's sights - on .22's, mid range rifles, and a couple I use for longer distances, one's a rolling block 45-70, it makes it to a 1000 yards with some to spare - for the dollar they get the job done. It won't make 1200 without help and guesswork.
I have a MVA like previously mentioned on another rifle, it's a very good sight, it goes out to a mile with a little room to spare, if you plan to shoot this in the future, don't hesitate, save your $$ and get one.
I am fortunate that I have the skills and the facility, wishing I had more time - I make sights for a hobby. I've copied many, from Soule to Snover, from Hammond to Maynard, a dozen of my own design to something as simple as Steven's and Pope's. I have a fair understanding of what makes or breaks a sight but it's just an opinion and everybody has one. The markings have to be clear, the motion has to be positive, the fit of mating parts have to be close and smooth. The more money spent generally wins these characteristics.
The windage feature is great, front or rear, but unless one has an exceptional spotter, it tends to create havoc - for me. A spotter that makes the call and really knows what going on down range - makes the shooter. They are few and far between. If I'm shooting without a spotter or someone that is marginal, I'll correct a minimal amount, study conditions, pay attention to the neighbors hits and misses and generally hold correction. If I focus I do well.
Good luck with your decisions.
