I wonder if holding the stick away from the frog offers a lighter more dancing touch then the traditional position at the frog?

Can you get a real lilt with the classical bow hold?

I was at a session last night where one of the fiddlers holds his bow about a hand's width above the frog. He is a very good fiddler, playing in several ceilidh bands over the years, and certainly achieves a real lilt. He was classically trained at school but then gave up for 10 years or more. When he started playing folk fiddle, he followed what the others seemed to be doing and adopted the unorthodox hold. He wasn't sure if there was any technical advantage but thought that it gave the lighter, more dancing touch suggested above. He now finds the orthodox hold gives a more stilted result.
