It may help to get those pdf's on paper. I can't imagine reading these on a cell phone. The only thing superior to being able to handle the physical book with the ease of flipping through back and forth from page to page is reading on a large monitor with the Ctrl+F search options. The index has always been very good too, but keep in mind that there is a separate index for each scale.
My own early mistake was printing out the Advanced Battleforce rules by themselves only, thinking, as others tend to do, that these systems are all independent of each other. With the exception to SO:AA (there's a reason these were split into their own books) you really need to read through all of Battleforce, Strategic Battleforce, Abstract Combat System and Inner Sphere at War to get a grasp of what the developer was trying to do. It's a tremendously huge idea and it all deserves to be considered as one game with several systems. Two small gears are still running larger consecutive gears. The small ones appear to be moving faster while the larger ones are moving more mass.
Dog fighting with aero will only wet the appetite to see them getting spewed out of a Dropship in combat.
