MI.sabot,
In Perklo's Example, a shorter front sight would put him closer to the center of his scale. A higher front site would have his rear sight way high off the scale. So if anything a guy would want a slightly shorter front site, but is not neccessary to have a functional sight. Mine are at the top end of the scale also, so I would suggest you try the standard front Fire-Sight and I think you will be happy.
Remember this, if you raise the height of the front sight, you will have to raise the rear sight along with it to stay on the same plane. This would put you way over the ramp on the rear sight.
If you install a shorter front sight, you will have to lower your rear sight to stay on the same plane. This will put you back down into the scale on the rear sight as long as you don't go too short, then you would be below the scale.
Of course this all pertains to what type of bullet you are shooting (heavy or light). I would say on most rifles you will be at the top of the scale with heavy bullets, slightly lower with the lighter bullets, but overall in the top half of the scale.
If my digital camera wasn't broke, I would post you a couple pics.
I guess that will be the first thing on our Christmas list.
Perklo,
I'll keep an eye out for ya!
I'll be the guy with a Huntsman that looks just like your Sidekick.
