dtroup64 posted he didn’t like the taper and the CF shaft was too thin at 11.8mm whereas he normally plays 12.5mm.

So to my way of thinking, until he tried a CF shaft with the same specs as the regular shaft he plays, it does not seem
like a fair comparison to give up on CF shafts. But if the hit, feel or sound wasn’t to your liking, all the rest is academic.

as you know, the material you have absorbs moisture, so it expands and shrinks, why they always look loose. I don't know if the material is the same now, but i wouldn't risk, buying the fibre stuff, if you can find some old ones. Or a trusted source, Theres your winner
Could you not just put the original one back on?
Here is an interesting thread on it, look at chris Hightower post 5:
