MS Trips leaves off some road names and mislabels others. There is also no automatic way to print cues. Anything over 25 mi has to go on 2 sheets or you loose detail. I just print to a pdf & live with it. It works well enough for weekly rides and is an improvement over hand drawn routes on copied topo maps. One of the TCM riders gave me a map generated from a GPS data download. I'd lean towards having my own copy as online sites are likely to change the deal.
I am a fan of MapMyRide. I used it for a Comfort Zone ride that I led a two weeks ago. I received very positive feedback from those maps/cue sheets. One feature that I really like is that you can give a detailed description of the route. Also, if there are places where riders should you extra caution can be mentioned in the route description. The 2008 Tour de Glade, the 2009 Tour de Nash and the 2009 Tour de Cure used MapMyRide maps/cue sheets. The fee for MapMyRide is around $48 dollars for a year ($12 savings over the $5 per monthly rate (there are other rate options)).
Please excuse me as I realize this sounds like a MapMyRide infomercial, but I am just a fan of this service.
