Hi BC. I wanted to ask some the experienced stringers on the forum whether a beginner can string a racket at 30lbs and make a good job of it? I want to get into stringing as I like experimenting with different tensions and strings but I don't have any experience at all. Would may racket be safe? I was thinking of going with the Pro's Pro Challenger drop weight as it seems more accurate than a crank and has a 6 point mounting system instead of just the 2. I would also like to ask about prestretching a string. I have gone through BC's archives and found that opinion is divided on whether it is a good idea or not. Some members say do it as it reduces tension drop but others say it decreases the characteristics of the string including the repulsion value. What are your thoughts?
