Well id have to say i have 3 special techiniques and they run at 3.5 volts and are rather quite quiet.
I do have a bishop and it runs at 9.5-10 volts its quiet but doesnt have the consistency of what my 3 special techniques.
i have heard the HAWK is quiet seen it used a few times by Dan Henk at a convention.
The only thing about the HAWK that is a flaw and a turn off for me was that the needles are only ordered through them.
i know its probably different now cause that was like 3 years ago but i know i want what i want and i have to say specialtechniques
will satisfy and run however you you tell Bill what your looking for.
i love how so many people diss rotary machines and have never tried them.
its difficult for me understand the negativity....something i guess i will never understand.
