There was the Masterline Chalkstream of maybe 20 years ago that was "bumpy" too. It cast great and I recall it being a really nice line that held up well but my memory of much more than that is cloudy.

There was concern back then over the "bumps" prematurely wearing guides. I don't know if that was a real issue or an imagined one. I do know that my 8'6" 6wt Orvis Limestone Special wore a Chalkstream line most of its life. I still have the rod and the guides look fine to me.
