I wouldn't exactly call it a version 2, it's more like minor upgrades. I used to have sintra thighs, shins, and shoe armor. Recently won an unfinshed set of JD legs from Cruzer's Ebay auction. You can clearly see the quality difference from the sintra to the JD's fiberglass. Upgrades to come include BKBT's fiberglass chest armor (sintra currently), and I have an MLC Arena JP enroute sometime next week. I have a complete picture posted in the image gallery.
The JP pictured is my original JP. I won't need it when I get the MLC, just putting some feelers out there to see if there's any interest, if not, I'll try to ebay it. Thanks JN
