They probably are not ready Mike. I like the idea, but like everyone else on here we are pretty open minded.
Most of the Trootmasters might not get it.
I do like a plastic spool for fitting lines to reels. I put the line on first, add the backing and wind until full. I then wind it all off again using a drill and a plastic spool with a bolt / wingnut through it. I then transfer it to another plastic spool using the drill and finally hand wind it on to the reel again. A long process but it does maximise the amount of backing and does not rely on reel makers "guidlines" which don't account for backing diameter.
