Perhaps not too surprising that Flemski went down to a defeat against a good team, but it is still the kind of match that you perhaps would have hoped they could have pulled out.
Seem to be not in the greatest of form at the moment so perhaps dropping back to a challenger to try and get some wins going might not be the worst idea in the world.
Not quite happeninmg for Flemski at the moment but I wouldn't be panicking. I'm not sure that they are not maybe just a result or two away from getting their season really on track. I certainly don't see really particularly bad form.
They have had some hard or as I suggested here tricky draws. A couple of 3 setters in the Chennai semi ( MTB ) and Australian Open got way from them too.
I'd be for sticking with ATP where possible for now, but if they don't get wins in the next couple of months or so maybe consider some challengers.
However, for now, they have got to ATP level by their results and for me that is really where they currently belong and should play for now.
