It's incredible. It projects at least as much as the Magnacore Arioso D or Larsen Solo D, but it's brighter (not at all tinny, though), more responsive, longer-lasting, and much easier under the left hand; that is, if you apply the same horizontal force with your left hand, you will slide farther on the Versum Solo D. Nor does it buckle under pressure. Additionally, it has a very clear, focused, natural tone, not at all processed like Larsen D strings. Even so, I think it blends better with the Magnacore A than any Larsen D because of its brightness and clarity. The Versum Solo D is the most soloistic D string I have ever played. Note: there can be some surface noise for as much as a week after installing; totally worth it.
