This has been a much longer process than I had originally anticipated, but I'm real happy with the outcome. Figured I'd post this here, as well as my build thread, since folks frequently like to see slider picture threads. 
This pic shows that the mild tree bumper actually provides a pretty significant amount of extra protection, while keeping the truck as narrow as a fullsize Blazer is.
Hard to really see, but I like how subtle the sliders are.
The tree bumper tube has a slight upward angle to it:
The ends of the sliders are cut and capped at 45*. The Tree bumper tubes come off at a 30* angle. I may add a couple of cross tubes at some point to further support the tree bumper, but while I wheel nice crawling trails, I'm pretty gentle on my truck, so it's probably not necessary.
The brackets are from DIY4x, and include a backing plate to bolt to the body mounts. I will at some point pick up some fabricator's bushings and tie these into the frame as well with those bushings to allow for flex and avoid cracking the frame, but will help take the load so the bolt holes in the body mounts don't wallow out.

They're bolted on the floor support. But, like I said, I will also add some frame-to-slider mounts with fabricators bushings to make it really nice and solid. Exactly like what Badmix has done. Also, your picture isn't working - at least not on my computer.
