I'm considering trying either one of these strings and have a couple criteria I need to meet before I drop the money. I need: Tight lows, punchy mids, highs that sparkle, but most important is string feel. I don't want something that will hinder my playing or tear up my hands. I usually use Elixir but I'm trying to avoid coated strings as I need a crisper sound. So what are some of your opinions to those that have used them?
