It wasn't high RPM spin (like you get with open patterns) that was the problem with spaghetti racquets, it's that fact the ball comes off like a very irregular knuckle-ball. I remember doing this when I was a kid by taking some fishing line and wrapping it around some strings. You have control issues but can hit these weird unplayable shots that look like breaking balls
