Actually, I think they should emphasize more on a slightly different caracter between the start in Antwerp and Brugge.
In both cases skipp the first Kwaremont (especially from Antwerp they have to make some serious unnecassary detour for it), they can use the kilometers from this detour to make the parcours more interessting
With the start from Antwerp they can focus more on cobbled hills, so instead of going the Oudenaarden and the Kwaremont from Antwerpen, they go through the region called "Kouters". There are some interesting RVV type of hills, like the Putberg, Putteberg, Congoberg, Varent (all paved with cobbles) (and a few more) than they can approach the current route with the Bosberg and the one and only 'de Muur van Geraardsbergen' and connect to the current route with Berg ten Houte.
When they start is in Brugge they can focus more on the first half of the race with wind and flat cobbles. The region at the sea is more known for winds than the Antwerp region. And there are quit some interesting cobbles in West Vlaanderen already, they can easily connect with more known cobbles as the Neringenstraat, Herlegemstraat, Huisepontstraat, Doorn, Hollweg, Kergate-Mater, Ruiterstraat, Jagerij, Haaghoek, Paddestraat, Lippenhovestaat and quite a lot of more unknown shorter sections.
They really should change that boring final, were even there is barely audience on the roads. They could exctally use a part of the Nokere Koerse route. After the last Kwaremont and Patersberg, they should make the final esthetically more beautifully, but also a little bit more tactical. So after the last Kwaremont and Patersberg the do first the cobbles of the Varent, then some 'hilly' terrain with Holstraat, Petegemberg and Fabrieksstraat. To go back to Oudenaarden with some cobbles like Nokereberg, Huisepontstraat, Doorn, go through the Oudenaarde city centre and finish on the same spot as now, but only the riders arriving from the other side of the road. So, the best riders can still make a difference, but I think this final makes more variation in how the race will be decided. No its just pure force and explosiveness on Kwaremont and Patersberg which decides the race, but with a more 'rolling' final, some tactics can become important as well. Even the finish picture will be better with the old medievel city on the background.
