Just thought you might be interested to see this .
Start from 4:00 time mark... see Bruce Berry from Beulah explain how 3 different graphite modules 42 million, 48m and 52 m are used in the Platinum series.
Beulah platinum is one of my favorite rod series. great feel in hands plus super responsive and easy to "track" all the way from initial set up to follow through. Maybe it is due to those 3 module materials blending... I am not sure what other blanks are also doing this... any thought?
