Bill,
I think I can help, because I had the same problem when I first started. Two points: First, I would begin with a furled line since they are easier to cast for most people. Secondly--and this is the more important point--keep your casting stroke short--really just a "flick," with the rod ending high. Usually, coils at your feet mean that you are over-powering the cast and stopping too low. You say to yourself, "I have to get that line out there!" and you do the exact opposite of what you need to do. Think "gentle flick" (for a good-quality rod), stop higher than you think you should, and you'll be amazed at what happens. Good luck and hope this helps!
