I like MD-88's. With Delta short hops, it's usually that or an RJ. So, it wins on comfort points. You have addressed a group of experienced flyers. Most of us couldn't do our jobs without flying, although I suppose there's more than one John Madden out there. There is nothing to worry about, because something seriously bad almost never happens. Your fear, as I'm sure you know, is irrational. You should consider visiting a therapist to learn how to relax and enjoy travel. Or drugs and alcohol work most of the time, too.
