Thank you Karen, your reply seems to be the only reply I recieved
in this newsgroup and alt.support.hearing-loss.

I will summarize:

The solution for me turned out to both the ear molds and the hearing
aids.  The molds I had were soft with a seperate vent canal.  More
like my old molds, my dispenser got me hard acrylic molds with the
vent canal merging into the audo canal.

Using the DigiLifes with my old molds (what I was used to) did
not help though.  It seems the Digilife software interface (Noah
interface?)  was quite limiting in adjusting the left aid to my
complaint.   I'm sure someone more knowledgable than my  dispenser may
have been able to adjust the aid via the software to my complaint.

My dispenser let me try out some DigiFocus aids. With the software's
default programming for my audiogram the left ear sounded pretty good.
Since these sounded nice and the default programming seemed to agree
with my left ear I ordered these.

I realize the DigiFocus is a better aid.  The software interface is
different (better?) than the DigiLife interface though. It allowed my
dispenser to adjust it more easily for my left ear.  So that was
my solution; ear molds much like my old ones and the DigiFocus aids
with a minor adjustment for my left ear (less low freq gain more highs).
