You forgot the sarcastic smiley :Yes:
As for playing a record in reverse... I can do that without the reverse switch. And on technics.
Just takes practice.
Besides most of the skills thaT go to make up a DJ are not reliant on things like reverse.
Good solid DJing skills rely on practice, beat matching, musical knowledge, structural timing ability and EQing. Everything else, as flashy as it may be, is literally a sideshow. [accepting scratch DJs of course, thats slightly different]
