I realise that Maptitude is probably over-kill for most Streets&Trips users here, but some users may find the latest version (Maptitude 2016) useful because the Routing Manager has been rewritten. It is much more usable and has a feature set similar to S&T/MapPoint/AR. It even includes functionality that I had to implement in the RouteReader half of my MPRouteWriter product!
I say "overkill" - Maptitude is really a full GIS system, so it can do a LOT more (and a lot more than MapPoint). Yes it costs quite a bit more than S&T, but it is probably the most economically priced GIS on the market.
