Here's what I've been running on the 6R with quite a bit of success and honestly I'm surprised that I haven't seen this build on the battlefield. The trick is to almost forget the PPCs when you peek to minimize your exposure. This will help you take less return fire and keep you cooler for the moment when you decide it's time to attack. Just don't forget that you've got an XL engine and that your optimal combat range is about 200-400 meters. As with anything that mounts PPCs lights that get right up in your face can be quite annoying so stick with the group.
