850's suits are of lower quality and are made in ABS, which is unable to capture the sharp edges and details that are the hallmarks of the New Gen suits. They also have refused to accept feedback from the FISD and are unlikely to be approved at any level other than basic. I'd avoid them, but judge for yourself - one of theirs completed in-house on the bottom vs a Jimmiroquai suit on the top (admittedly mine).
Ah gotcha, those might work then if they have the right shape, symmetry, and raised/beveled coverstrips!
