XCopter, I think the first step to bridging would be setting up a print cooling fan. Clough42 has done a 200mm bridging in one of his YouTube videos, which included a print cooling fan (https://www.youtube.com/watch?v=-X20j_wKg6A). In my own experiences printing this fan mount, I recommend lowering the z-height on the mounting portion if you have a J-Head hot end. This way, the mouth on the funnel-like part that the fan mounts to is actually blowing on the plastic. I also recommend getting a high CFM, high quality fan, like a Noctua one (even though I think the color of plastic it's made of is absolutely ugly) (http://www.amazon.com/40x10mm-A-Seri...words=40mm+fan). If you're having really bad issues with the print not cooling, you'd probably want to find a way to mount multiple fans to cool your print. I'm by no means an 3D printing engineer, this is just information based on what I've analyzed.
