I've heard much the same thing. Below approximately 200 knots cruising speed, the added weight, complexity, maintenance and insurance issues etc. of disappearing dunlops is not worth it, compared to well-streamlined fixed gear. That's the reason that for instance the Cirrus has fixed instead of retractable gear. (Plus, in the Cirrus the fixed gear is an integral part of the BRS system, to cushion the landing.)
As for VP or CS, always a good idea. Even better if you combine it with FADEC like on the Diamond or Liberty. Although FADEC does mean a greater dependence on the electric system. (Discussion already underway in another thread.)
