Reply to Tips for mixing top-40

Would like to hear any interesting tips for mixing top-40 and requests with traktor fx, besides echo-freeze. I started mixing house and trance back in 2000 and stopped for a bit in 2007, came back and now have a gig where I have to play top-40 and heavy requests (I dont like playing this way!) have crazy bpm jumps depending on what people want to hear (and this changes dramatically each week)

Any help would be great
