I've been polishing some of the tapers lately and have a new base curve for the 6' 3" models - a #4 would have the following #'s: tip - .070 05 - .079 10 - .095 15 - .117 20 - .134 25 - .144 30 - .159 35 - .182 40 - .194 45 - .203 50 - .216 55 - .227 60 - .237 65 - .247 70 - .253 75 - .253 Now if you run this through a 'hexy' program and compare it to the curve of the 7' 6" - the curve for this rod should be just a foreshortened version.
