Yes mate its the old way of numbering them MT = Medium Taper8 = the # of wraps144 = the length in inches.Then there were / are the FSU's SU's FT's & one other I think that eludes me now. Am going on memory here, remember I'm old so cut me some slack if I get this wrong, but the FSU is a Fast Surf, SU = surf, and FT, well that has to be a fast taper.Surprised to hear they are no longer made. I have seen a few, especially the 7wraps, in various tackle stores. Might have to pay Pillie another visit @ ABT and grab the couple he had there in case I want to rekindle the youth and replace my sabr
