looks like a really nice haul there, i have 2 of those mats and they are the best ones out there for the money, i wish i could afford to plaster the full space with them but they are expensive.
2 of them manages to cover my power rack and give me enough space for deadlifts, which is quite frankly enough, so i have cheaper thinner rubber matting instead for other work which is adequate.
only thing missing are these imo

they are great when you hit plateau's or want to break a PB, etc. well worth the money even though they are so expensive for such little weight.
would love to see pictures of your setup
Interesting, will look into getting some of those fractional plates, should hopefully have everything set up Saturday afternoon so will get some pics up.
