I'm in the same quandry for the same reasons, so I just finished reading Chassis Engineering by Herb Adams. I couldn't make heads or tails of all the differing opinions, so I decided instead to educate myself on the fundamentals of WHY different systems work and what the compromises are with each system. It sounds like you're on the right track (from my still rudimentary understanding). I'd like to get rid of some weight rather than add it, so I'm leaning toward the 3 link since I don't mind the fab work.
