Stretching the Treble

[mps@usol.com]

I have been "tuning" for several months now. I know that this isn't 
very long but there is no sense in continually turning out tunings that 
just don't sound right in the treble.
I feel I have a good enough ear on this matter.
I tune aurally and would like to know what partial(s) to listen for to 
make this stretch sound more accurate.
I have no trouble in the bass, only the treble.

Thank you for your time
