New play shaft called the 'MUST'. i contacted them(man they answer fast) and was told that it uses a higher grade of CF and also uses a different 'core' as he put it. Didn't go into detail but he said its lower deflection than their standard cf shaft so i'm guessing the front may be hollow like a Cuetec. Also comes with a Nishiki tip. Only two shaft sizes and four pins. https://rhino-billiards.com/products/rhino-710mm-28-5-16-18-carbon-carom-single-shaft-12mm-copy
