Typhoon "Constant Taper" means that the poon is spread evenly over the entire length.
I think Sparky was almost on to it with his statement, but mispelled a word. I corrected the spelling.
Aldila NV shafts are constant taper, perhaps the reason they've always felt great/played great, even when the mind says they do not fit in my bag. Might be because the different 'zones' are blended to make a smoother overall shaft. (??)
