as title cheers
CLX-I was the original version, the CLX-II has had several changes as follows:
Smart Clamps
Woven in colour change to base of each section, including the handle along with joint indicator tape
Removable end cap to allow for the addition of extension sections
The CLX-27 now has 65% carbon fibre content as opposed to the 50% that the original had - this gives it as good bounce suppression capabilities as several competitors full carbon poles when tested recently
