Hardi uses only Thomastik Dominant's, BUT with a Pirastro E. A lot of people use those awful Super Sensitive abominations. Make a good fiddle sound like a fishwife. Try switching that E to a Pirastro and see what happens. Couldn't hurt. And if you are used to playing in sessions, try slowing down to develop your touch for tone, and then speed up again. Not saying it will do as much as a fiddle upgrade, but couldn't hurt.
