I was thinking about this SST cuetec shaft and the story again, I really enjoyed it but I gave it another thought. I think during the videos I posted which was in 1990 and 1991, at that time I don't think there was an SST Shaft. If I remember correctly these shafts came out much later maybe 1998+? Someone can correct me on this but I owned multiple cuetecs back in the day, the shafts were fiberglass and looks the exact same but they did not have an SST logo in them. Some of the ones I owned were thinner than others, some were 13mm thick shafts. I still remember one of the best cuetec fiberglass shafts I've owned was a thinner fiberglass shaft with shorter ferrule somehow I played really good with that shaft. And it did not have an SST logo.
Just to reference the story teller above about Earls shaft, maybe it was his shaft later on when he owned the black cuetec shaft, but not from the Early 1990's to 1995, because back in those days he had a cuetec shaft without a SST logo.
