I saw someone asking about them on myArmoury too, but I don't think we've gotten a real side-by-side comparison with other legs. They certainly look pretty, but then it sounds like most of the MRL armor is hit or miss in terms of the quality while always looking pretty (for example the gaunts are photogenic, but I hear they're pretty useless).
I got a chance to handle the legs from Revival Martial Arts (
revival legs), and they're fairly thin and light. Depending on what you want to use them for, this could be good or bad. They're probably too thin for SCA use. But they seem combat-worthy otherwise, and articulate well and seem like they'll fit most average leg sizes. They also come with very simple gutter greaves that actually fit me.
The CAS/Hanwei legs are thicker and heavier than the Revival ones, and also seem to fit thin to medium sized legs.
I'm hoping someone will buy the MRL legs so I can take a look and have a comparison in my head.
