So I'm thinking of getting a hitting net so I don't have to go to the driving range so much, but have heard some scary things. Some say it's real easy to groove a bad swing when you can't see the ball flight. I still intend on playing regularly so I should notice any weird changes. Still it's got me wondering. I know the benefits would be that I could practice my set up and making solid contact. Just wondering if these nets have helped, hurt, or not affected your guy's game.
