Excellent.
Do watch out for one quirk of the 'pull the route around' method.
There is a bit of a knack to it. You might notice that if you start at one end and drag the route, then drag it again, your first drag might move, too. The reason? It's simple:
You start with one single route, going from A to B, maybe over many miles.
You drag one bit, changing it to A to C via B
You then drag it again, making it A to D via B and C.
The clever device works out a 'better' (though not where YOU want to go) way for you to get from A to C and on to D by missing out B.
One method of reducing the chances of this happening is to make your first pull of the route reasonably close to the middle of the route and then work out from there. If you look at the roads, it's sometimes possible to second guess where the computer will pull your route through. For instance, there is a very good chance it will always chose the fastest / most direct roads, irrespective. Anticipate this and make your drag onto the lesser road(s) to give the device a clue. Another example might be where the computer generated route takes you through a town, when the more 'sensible' route would be to take the much longer (but ultimately probably quicker) very nice ring road the local council has spent a lot of money on. Practice makes perfect.
Another tip is to have a big screen to work from, as opposed to an 11" laptop or mini-computer. The big picture is often very helpful. Getting to know and love your zoom and detail tools, too.
Always, irrespective of what method you use, check your route after completion. It's a good idea to run 'recalculate' too, before you do so, just to let the computer jiggle itself about. Then check you are happy. Checking should highlight any glaring errors (small side streets chosen, or clicked nearby by error, and bizarre short cuts) and above all give you a feel for where you will be riding as and when you do set off.
Last of all, check the routing preferences you have set. If you have told your computer that you really do want 'twisty roads' it WILL do its best to find them, every time, without fail. This is annoying if you really want to go from A to B (via C E G and W) down other straighter or more direct routes. It will screw up your pulling around no end, leaving you ranting that BaseCamp is crap... When all it was doing was acting precisely on your instructions. Customers asked for a 'biker' or 'windy roads' feature to be added, chiefly as it stopped them having to think or look at a real map for themselves.
