I may mount the Hayes Research and Troy flip-up front on the same rail for comparison.

If you're going to measure, get or borrow a set of calipers and measure from the bottom of the mount (the rail top) to the middle of the apeture (rear) or post (front) and compare the measurements. If indeed the Hayes are standard height (which they don't look to be) then the problem is how you're aligning your hat rack to get your sight picture.
