In reply to Jimbo C:
Yes, sure I also do it myself, the thing it's, that I feel it's like constant chalking, one can end up overdoing it, even when the move it's not that hard, or when in spite of dusty-white hands, the manic-chalking goes on and on...
In that sense, I really appreciate how Nalle keep it all under control, he even doesn't need the chalk-bag!!!
All in all, pretty good news, for the question (Is it possible to go further, on the high-end bouldering?)..It looks like a YES, just watch this guy on one of the hardest boulders out there..
Cheers for that!
