I ditched the idea of having RF 70-200 due to its long and cumbersome focus ring.

Curious what this means?  Had me take out my 70-200 and try to understand (admittedly haven't MF'd it much to date).  The focus ring appears to be of average cumber.  I'd call it narrow rather than long.  If you mean focus range, it takes around 3/4 of a turn to go from close to infinity focus when set to linear.  One advantage it has over the EF is you can set it up for variable sensitivity based on how quickly turn and that has it go from close to infinity in less than half a turn, easily.
