Looks like you have all of the pros and cons listed already, so only you can decide what to prioritize.
Both me and a good friend have SB130s. He put on an ElevenSix coil and loves it. He is faster than I am, both up and down and does not mind the weight or slightly less climbing efficiency. I have stuck with air, because I need all the help I can get on the climbs - but did just upgrade to the new Float X last night.
My personal feeling is that if you prioritize speed on the descents above all else, the coil is the way to go. If you are weight conscious or want a really poppy bike, go air.
