re: seats, I've rather liked the less extreme of the Specialized Body Geometry seats. most of them come in several widths, as my sit bones are relatively wide, so I prefer the wide ones rather than the skinny. I haven't bought one in a few years, and of course, all the new ones are different, but the Avatar Expert looks like the sort of thing I'd put on a road bike for non-racing duty. A specialized dealer should have a saddle fitting thing you sit on to determine where your bones are and which seat size would be a good fit.
I rode on Brooks saddles in the early part of 1970s, and when Avocet introduced the first of the modern style saddles circa 1980, I couldn't wait to switch. I still like the classic Avocet Touring II, there's one on my 1970s Motobecane Grand Record touring bike, i rather wish someone still made seats like this.
