I just got a gently used set of Genssler Wraps from a fellow TBer, and I have a couple of questions. First, in general, should I make new maps every time I experiment with different strings? Second, my best maps have been made arco. These things suck arco. They're good enough for my daily vomit, scale, and intonation practice which, aside from the occasional final note on a tune, is all the arco I do these days. Should I go ahead and use the bow for some maps, or just make them pizz only? I'm hoping someone has some experience here and can save me some time. The only thing I dislike about the Dex is making maps, which I find quixotic and tedious.
