shane does too. in snooker john higgins has it. seems to be a thing affecting PSR/back stroke but not point of contact or follow through
There used to be a guy in my dad's snooker league who was playing in League one until his late 70s, developed tremors in his 50s. His surname began with Tre, and he became known as 'trembles' for 20 odd years. I only ever knew him as 'trembles' as I would go to watch Tuesday league (single frame 5-a-side team matches) because my dad couldn't find a sitter. I watched 'trembles' make more than a couple hundred breaks.
Point of contact is all that really matters in the grand scheme of billiards. Michael Holt did a funny short video about this. Blasting in a length of the table blue and screwing back the length of the table, waving the cue around like a fencer after contact. Of course routines and habits make that more consistent, but look at players like Alex Higgins (or pagulayan to keep it pool related), who wobble like ADHD kids with a cheek full of blue smarties. Can't say they don't get the job done.
