Saint Brieuc is such a great place to go for a trip even to see this challenger event. There are several interesting players to see like De Schepper, Lacko, Berrer, Gicquel, Mahut, Authom, Kunitsyn, Mertl, Meffert or Nedovyesov just to name some. I think the list is pretty good.
Besides there are several places pretty close to visit like St Malo, Quimper, Brest, Rennes or Nantes just to name a few places.
Therefore I would take one week off to go there
There's nothing interesting about De Schepper or Authom (and Nedovyesov, I guess)
Unless you like serve-dominated games.
