The final climbs on stage 7 aren't much but at least a couple of them are enough to try to get away if there is a strong group or if time gaps are small on GC. It probably won't be selective but there is at least a platform to try to make it so; some of the roads on the closing circuit look to be quite narrow, maybe you or one of the other Dutch posters here could confirm?
Stages 5 and 6 look to be very solid, plenty of opportunity to be decisive, and stage 1 depending on route could be echelon heaven. I agree the TT should be around 15km to suit the parcours, but overall I think this route does a good job of utilizing the two countries.
In an ideal world, I'd have an Eneco Tour with about 15-20km against the clock, a Belgian Vlaamse Ardennen cobbled madness stage (probably wanting to use Mont-Saint-Laurent/Côte de Beau Site since none of the Flandrian races do and the one day races that DO use it don't have it anywhere selective enough), an Ardennes stage, an Amstel Gold-lite type stage in the Maastricht area, a real coastal stage with echelons being an almost certainty, like a less dangerous version of Giro 2010 stage 3, a sprinters' stage with a technical run-in to allow the possibility of late attacks to have a chance, so that the sprint is likely but the full trains are not so likely, and then an a mostly flat stage but with a slightly awkward set-up with a rolling course, maybe somewhere like Nijmegen (Ubbergse Holleweg and Oude Holleweg used on the closing circuit perhaps, but about 12-15km from the finishing line ideally, a bit like Waseberg in Vattenfall). That for me would be an ideally suited route to what the Netherlands and Belgium have to offer, and have something for all types of cyclist except the pure climber.
This route isn't perfect, but it does do a pretty good job of offering everybody something to play for in the race, which makes it completely open in terms of GC and you can't really ask for too much more than that from the race.
