"Upgrading" a Tak focuser is actually DOWNGRADING - they hold a metric tonne of weight - easily 5kg in a zenith position without any movement. I had a Feathertouch on one FS60, and whilst it made life easy being able to use 2" accessories, it slipped at any angle above about 60° with a 3kg weight on it.
My advice, is leave it as is. The stock focuser is FINE, albeit VERY short travel. You WILL need extension tubes of some sort.
I have a Tak FCT-100, and once that thumb screw is tightened, I cannot move it even by PULLING on it.
