Hi Klaus
At least according to my opinion there is no excuse for any chipping at all, no matter what time period we´re talking about. Natural line is natural line and if there is any boulder part which seems being unclimbable, thus there is no other way than wait for someone stronger. To chip even one hold which can be skipped if someone stronger comes is no solution for a future. I find it very close to artifical walls...why not to screw on some hold then???
Anyway, many thanks for cleaning works on Loucovice as well as for heaps of new problems opened...

Thank you for your promise on no more chipping. 

Bye Michal
