Crappie Reaper. You are scaring me dude. I've got four prototypes of an in-line spinner in my drawer. We think a lot alike. The only thing I can't get my head around is how to change tubes quickly. (Like on a Road Runner.) If you can't change the tube quickly, it just not what I want to do. I turned one of those over to an engineer friend of mine and that was three weeks ago. The easy ideas like a "snap" is an invite to catch grass or moss and come and gone. We think alike, just hope you don't look like me.
