Props to PMU for at least taking the time to put his position down in a reasoned, articulate fashion. He may be an opinionated s.o.b. but a least he takes the trouble to make his case, albeit a case frought with suppositions, supperstition and plain FEAR!
Me, I've never flown inflatos. I'm an S and G arc guy all the way, and have never regretted it. In one and half seasons, I've learned faster, progressed faster, learned more tricks and boosted higher than most others I've know.
I've repaired my arcs exactly once in 1 1/2 seasons -- I had to apply some spinnaker tape to a 3 inch gash. Total time: 3 minutes. And I've botched more than a couple of launches and landings on account of my own stupidity, and the kites came through with flying colors.
Relaunch? A snap. Bridle tangles? Not a chance. Bladder problems? Only my Grandpa..
Just my 2c.
Fly what you like. Fly safe. Don't be a dick. Share the stoke.
