I've had some pretty interesting MED variations over the years too. There was one on a mono core that was 150 feet long that both Rick and I cast to the backing knot (I suspect Rick cast it beyond the backing knot), and one taper variation on the standard core in particular (that is probably still in my truck in Nova Scotia) that I just loved. I don't know what the difference in that one was but they weren't numbered and so Bruce and I never found out

One thing I do know is that there is a better all around distance line waiting to be made, because both manufacturers have already produced better prototypes! The differences aren't huge but are significant.
Cheers, Paul
