That being said, my most rewarding tuning 'work-outs' have been with good bass trombonists;  either in an ensemble, playing excerpts, or just Rochuts (and the like) in various octaves.  That's an important relationship to foster--  not just for intonation training, but also for a future professional life, where playing well with bass trombonists is bread & butter.  
Oh yeah;  it helps to play a little bass trombone yourself, too!
