"Why would anyone buy those lower quality chinese crap pieces?" Simple, money talks. Many paintball players don't mind buying cheap then replacing that item w/ more cheap ones three times over before hitting the price point of quality gear.
I'm not saying the idea is bad, just that it isn't likely profitable for SO to keep an inventory of these designs.
Case in point: a few years ago, a former SO soft goods designer developed a plate carrier called the Scorpion Prototype. It's featured on the main page for Blackcell as a matter of fact: LINK. The reason it never made it into production was because it was cost prohibitive - the time/material required for each vest would've driven the retail price too high. Lucky for me I managed to snag it a couple years ago during one of their famous SO Soft Good Sales they used to put on in the BST's here on the forums. I love the thing & have used it ever since. LINK to the page in the Player Gallery w/ pics of the vest.
I appreciate the discussion - just that SO does a great job of designing one-of-a-kind paintball soft goods, not rehashes of items that are already out there. Again, if someone wants design number three w/ custom Interlock panels on the back or other custom work, then SO would be happy to do the work.
EDIT: link to pics added
hey ger, could u please post some more pics of that vest of yours?
