[Harp-L] Percussive tongue blocking

[Sheltraw]

This is probably a well worn topic here but it's new to me. So here goes.

I have recently been using octaves in my chromatic playing. To play an octave one, of course, has to tongue-block so I can't use any of the tongue-related percussive effects that I know. Throat-based percussive attack just doesn't seem to sound near as good as the tongue stuff. 

Anybody have some tricks to share that give good percussive attack while tongue blocking an octave?
