Barcelona is the 4th biggest claycourt event on the circuit in my opinion, ahead of Hamburg. The facilities there are excellent and it has a rich history.
The downside of this event of course has been the lack of/non-existant coverage/live streaming available in the past. I'm not overly optimistic on that front this year.
You consider consider Hamburg to be a Clay court "Event"
... Lol just kidding, nah Hamburg is such garbage the courts are worse than some social clubs ive seen, and its barely a true clay court in terms of the bounce, historically the guys who do well at hamburg dont do as well/win RG, sortta similar with Rome, cos its so fast most of the fast court players do well there and die at RG. Barcelona and Monte Carlo are usually the biggest indicators of how they will do at the French.
I reckon after Wawrinka its a cakewalk for Nalby, Although Wawrinka is such a troublesome player for him dang it!!! I want Nalby to be in the final.
