[Harp-L] Throat Vibrato on Bent Notes

[Tony Renshaw <tonyrenshaw@xxxxxxxxxxxxxxx>]

I am after advice as to whether I should persist with working on throat 
vibrato on bent notes, or whether I should rely on hand vibrato for these? 
I am unsure whether I can still get a good hand vibrato when playing 
amplified with a microphone in my cup,  as I am not at that stage yet, but 
wish to have all the skills applicable for when the time comes. All advice, 
except give up greatfully received.
