So the "New Old Stock" La Bella plain gut G and D I won on eBay for $50 are due to arrive today. This will be my first-ever string change on a DB, so I'm a bit nervous. I've read all the threads on the subject, including David Gage's, but all of those threads describe changing strings with silk-wrapped ends, which I assume the plain guts will not have. Do I need to do anything different when dealing with plain gut strings? Are they more or less prone to slipping, for example? Should I twist them a-la Gage, or run the end twice through the roller, as others have suggested? Any tips from you experienced gut wranglers would be much appreciated.
