When playing 13th chord, there has to be a compromise. 7 notes, 6 chords. It's better to drop either the 11th or thr 5th. You must keep the 7th and 3rd. The 9th is truely optional, throw it out when the chord sounds to strong. You can't drop the 3rd because then you don't know whether it's major or minor. You can't drop the 7th because then you could be left with a (maj/min)6/9 chord.
If you playing in a jazz band, it's not uncommon to leave out the root and just let the bass play it. That might help also, but check the sound to make sure. In jazz the bass won't stay on the root for very long so that might be a problem.
