Glad to hear you got the email Harry I did pass it on for you.
I can tell you that there is the MrotatorHDelta which is a telescopic fibreglass pole system and an upmarket MrotatorHC which is a "Pull-Over" version made from Carbon Fibre. How the "Pull-Over" version works is a mystery to me until I see it working. The third version is also a Pull-Over version made from Fibreglass.
We will see when Agnos updates his website.
