In reply to Aaron Lines:
I've only been the once, in 2010 I think it was, and whilst I do think the grades are on the soft side, I didn't think they were ridiculously soft. Indeed, some areas seemed to have pretty stiff grades. I recall a pair of 6a's at symplegades which were really tough. As said above, it is often said that the route gradings are coming into line with other areas. Interestingly, my normal max onsight lead grade is a lowly 6b and that has been the case in the UK, various places in France, Sardinia, Sicily and ... Kaly.
A final thought, I do think that the mental side of sports climbing is often overlooked and Kaly is generally very well bolted. So the climbing often seems less serious than in other locations and perhaps that makes routes in Kaly just seem easier.
