As with Ross, I NEVER use the spring clip in any of my reels. For me it creates more problems than it solves. I learned that you HAVE TO clip the film in center. If you are off-center just a bit, the film won't roll properly and may/will kink. And you have to be careful to not push too much film under the clip or it will not roll well. So I just slip the end of the film into the center of the reel and start winding.
