Full development for the traps, than try cleans and/or Hi-pulls (either hang or PR). Hitting the complete diamond shaped trap structure, to mid/lower back. Also hits the lateral and rear delts strongly. For BB'ing DL's, might try rack pulls, starting around knee level pin set. Only need to start from the floor if into PL'ing. And of course , never going to complete failure on anything.
Even if your a big time DL'er, you should feel a soreness in the traps/mid-back the next few days. Good Luck.
