Soon, Pete G, you will do away with those wrappings and join the solemn, lonely ranks of the Plain Gutsters. Welcome to a Life of Misery.
No, really, I think you have asked another one of those questions that has no answer.
(The most infamous question being "What kind of steel strings can I put on my bass that sound and feel like gut strings?")
(The second most infamous is some kind of strange quantum mechanics equation/riddle where the money you pay for a bass is directly proportional to the somehow-quantitatively-measurable sound of the bass.)
There are too many variables--bow, weight, rosin, hair, strings, etc.
I still have not found many answers. I think there are none.
TBer Jason Sypher, who has since defected to the Rebel Steel Alliance (You'll be back, Good Prince Sypher), once gave me good advice when I was looking for some gut bowing pointers. He said, "get a quality bow you like, and practice."
