What did you do to stretch the Martha Marie? In my experience, it's hard to stretch the PHY tapers without doing some dimensional graphing. I really love that taper and now that I just got back into building blanks again, it's the next taper up on my bench (as is). I already have a Para 15 copy (the big brother for that taper) that fills my 8', 6wt niche. I do plan on making a Dickerson 8014GS in the near future, but after the Martha Marie taper, I'm going to make a couple of 7' 4wts for fishing the Smokies next spring.
