Like Micky, I find many of the beads too small, and I like the 3/32" with a white, or silver bead, plus a flip up moon bead with Warthog Ivory insert, but with the thin blued steel walls of the tube showing around the Ivory bead! I like the hight of the beads so that they both rest in the bottom of the wide-V rear sight!

I like the first flip up rear leaf to be cut to the same depth as the standing wide-V, but cut in the "U" Notch so the small front bead rests in the bottom of the "U", for percise, first shot placement! Once you get the front sight you like, have another one made, for a spare!
