I hate to say it, but the only thing I've ever found helpful in choosing equipment is gigging with it. Looking at the churn around here might suggest others find the same ;-)
I bet most of the stuff you've listed would be pretty good, so maybe just focus on the one thing you think is most important, and buy what does that best. Like, it sounded like weight was important to you, so I bet if you got the lightest thing you've considered, it would work pretty well.
I've actually been trying to figure my stuff out for a few years, and still wonder what the frick I'm doing
