Before I am admonished, I have skimmed through the major threads that are dedicated to answering this question. I am looking for straight forward, practical advice from the pros that post here. My son is a competitive junior player (12s) and, while he doesn't blow through string, he needs a restring every month. He uses Xcel, but would experiment if I could string. I am all in to learn, but have limited working knowledge of how to do it. Should I spend a little? A lot? Advice please. Budget-under $700.
