recommended to avoid excess spittle inside breath sensor

[wshNPC]

Is there a best playing technique to avoid spit build up within the instrument?

Playing style, tonguing style and angle of instrument matters. Tonguing should be done against roof of mouth behind the teeth, not against mouthpiece. NuRAD should be played at an angle of about 45 degrees or more (see videos of Masato Honda playing, he is holding it the right way). All this helps keeping spittle away.
