I prefer the TI strings but have always been a little disappointed with the G. It sounds duller and softer than the other stings. I've used all three gauges on various style mandolins and have the same result. I've also tried Optima's equivalent and find the G is also not as bright or loud. I've thought of mixing in a flat wire G from LaBella or D'Addario as they don't have the multi core. Some of my gigs have been 3 hours plus and the round wounds make my fingers sore after about an hour. Does anyone have a suggestion?
