HOPSTER,

What turned me on to Matchdot was a program on Sportsman Channel where they visited the pistol line at Camp Perry. All the top competitors were using them.
To be honest, most of the time I use the Matchdot II set on 2 or 4 MOA dots. I haven't used the reticles much. Indoors, there's no need to change anything. Outdoors, with lighting and contrast changes, its nice to be able to compensate. Also, if its too bright, the Matchdot has a polarizer that lets you selectively darken the target so the dot doesn't wash out.
For .22 matches, the elevation adjuster is, obviously, redundant.

My club has centerfire games where we have to shoot at 10, 25 and 50 yards. Its of use there, and on the silhouette range for 25, 50, 75, and 100 yards.
Here's my Hi-Standard with the regular matchdot. It has the four different dots, and no elevation knob. Got it on a Midway sale and it works fine, too.
And, I've just installed a rail on an old 29-2, which will be getting a Matchdot II if it ever arrives. This one will be set up for bowling pin shoots.
