Fiddling is rife with 'folkoric' characters. I remember one very accomplished and intimidating oldtime fiddler telling me that "Mississppi Sawyer" did not have a C chord in it. I (not nearly as accomplished) told him very politely that when I played it, it did have a C chord in it.

Stick to your guns. Rosin left on the fiddle collects dirt and crystallizes the the finsh (not good). However, your teacher is right when he says, "don't worry so much and just play the music". Trust your ears and let them be your guide. There is no one right way to play tradional music, no one right answer, no one way to hold the fiddle or the bow. Classical posture, though is very worked out and very efficient particularly holding the bow. As far as Jerry Holland antipathy, many folk musician get jealous when someone makes a living at a what for most is amateur vocation.

I've heard that Alistair Fraser used to be adamant about holding the bow in only classical stance all the timne, but since he started playing CB stuff, even he admits that he chokes up on the fiddle, too.
