Howard,yes musical immersion is a good idea,However I prefer to immerse,myself in the scottish style of hornpipe playing,rather than the Irish,which is difficult because I live in Ireland,and when playing in sessions,have to go with the flow.
my favourite fiddle player is Angus Grant[the left hander with the tassle]http://www.youtube.com/watch?v=ADyHCb8q7eM
