However Ray, I don't know about the Microburst. I probably shouldn't comment having not used it, but it just seems like another gadget to buy and take along.
That is my thought as well. I have the 72x20 XLite so it is a bit smaller, but it only takes about 15 deep breaths and about 1 minute to fill to a comfortable level. I do usually put in about 18-20 breaths and let some out to get it just right, though. Inflating it has just not been an issue at all. Even when I was suffering with fluid in my lungs at altitude, while it took a bit longer it still wasn't any real inconvenience. Given that it isn't a problem, I don't see trying to solve it by carrying another piece of gear.
Granted that is just my opinion and maybe I am more full of hot air than others here.
