That is really funny. My bad. I clicked through on the link and just saw the set at the top of the page. I actually can speak to part of the set you are talking about. I have the Iron Woody Fractional Plates and they are exactly what they say they are. I use them on a regular basis. They work great in linear programming.
I have never used the rebar bumpers which probably is a little more important.

Let us know how they are.
