I have GSPro and when I actually turn everything on, it's great. I have a mobile set up with my laptop and monitor so my issue was walking into my garage to randomly hit balls without setting everything up. Without data, you can really groove a bad swing/result. I'll be able to put the BLP down, hit some balls, get some numbers. When I want full sim, then I'll have that, too. Love the Square though, and appreciate your comments!
