This is pretty much the problem I had with the Orange Whip. I started practicing with it before taking my first lessons. Because I learned very bad habits swinging the OW incorrectly it took much longer to get a correct swing right. Then, following that, I noticed a strange pattern: If I warmed-up at home with the OW beforehand I could almost count on having a bad day at the range or playing.the people from Superspeed say to go all out with the sticks but they fail to mention to keep proper technique too.
Finally figured out I was reverting to bad habits with the OW, and that would carry over into my practice/play.
