I use the new matrix steel-pin and really like it. I modify them so that my 20 yd pin is green. I also modifiy the site so only my 20 yd. pin illuminates for night hunting.
Spot Hogg makes a great sight. If you are not set on the verticle pins like the TR has, I would look at the Copper John sight first and then the Spot Hogg. All three are good sights, it boils down to personal preference.
Check out my Homebrew Projects Page on my site to see the modifications that you can do to your Trophy Ridge sight yourself.
