The ridewithgps looks perfect so far. I am able to zoom in on the climbs _BEFORE_ riding the route and can determine how difficult they will be. The zoom feature in the elevation profile was the missing feature for me in Bikely (plus the route drawing was dicey). The only issue I have so far with RideWithGPS is while creating the prospective route online. It would be nice to add or remove points in the middle of a route instead of backtracking to change the route. Maybe I'm not using the tool correctly...
Glad to see the continual improvement with the tool Cullen!
