To me a "skilled" dj is guy pushing the runtables to the extreme limits, like the DMC dudes... So it has nothing to do with techno most of the time.
I just think we have gone over the step of how many records and how fast records a dj can beatmatch at the same time .... I think people like Sims, Carola and Beyer are the most tight on the three (or more) decks.
But whats the point ???? Mils and Bone (and many others) have been more interesting becasue they dare much more tricks and use the turntables as real instruments. Beatmatching has just become pointless, softwares can do that and allow to concentrate more on the musical selection.
Though the lack of tightness thewe last days, Mills stays my hero, probably just becasue he does new tricks avery day ! A lot of others can probably do best but have just copied the initiator (that could also apply to the production hehe)
