Tilting is great. In my review linked above, it shows the stability rod's attachment. It's really well made. Very sturdy, and still flexible enough to tilt. The rod sits in a pouch that's on a belt clip. So there's felxibility.
Weight and distribution would be an issue. The MultiRig Pro has lots of attachment spots all over it for stuff. But if you're loading it up with a ton of stuff, you'd want really sit down with it and plan it out.
I also like shooting with just the spider base by itself. Just two handles at the right angle, and it's effortless. Just like a Fig Rig.
