I too like the variety offered by a greater Walloon focus here, but I think this race should be closer to Brussel than Omloop is. So the latter should go back to Gent - Gent, and then the Muur could feature here.
I agree, that the omloop should finish in Gent. I think there just is a little bit of a disbalance since De Ronde moved to Oudenaarde in the variety of the classics. I mean:
E3 Harelbeke en Kuurne are finishing less than 5 k from eacht other. Then there is Waregem (dwars door Vlaanderen) en Nokere koers that are finishing very close to each other and just 15k more to the north than Harelbeke and Kuurne. Then there is De Ronde now finishing in Oudenaarde which is close to all the 4 finishing places of the other classics. And then there is the Omloop who took over the old final of the RVV.
So, I think it make sense those smaller races are looking for some variety. For me personal especially the E3 has lost a bit of his charms with not having the monopoly anymore on the Paterberg/Kwaremont combo as final.
I terms of variety I think all those races could have a bit more of there own identity if:
-De ronde moves back to finish somewhere east (Ninove) as it used to finish (although routewise more is possible around Oudenaarde) and having the monopoly on using the Koppenberg and having the Muur in the final. ------> finish east of the flemish ardennes
-Omloop moves back to Gent ----------> finishing north of the flemish ardennes
-Nokere focuses more on having a lot of cobbles than specifically having the most dificult hills of the region -----> finishing northwest of the flemish ardennes
-Hareldbeke will have the monopoly of having a Patersberg/Kwaremont combo in the final ---------> finishing (north)west of the flemish ardennes
-Kuurne focus more on the hills of the Pays des Collines and the (very) small hills around Kortrijk (maybe they should even move the finish to Kortrijk) ----> finishing (south)west of the flemish ardennes
-Dwars door Vlaanderen is a bit more tricky to gave an own identity, maybe the should try to avoid using the very well known climbs and use some lesser know hills in the Flemish Ardennes. ---------> finishing (north)west of the Flemish Ardennes
