After my experience today with a 2x teleconverter, I'd go with the 300 prime.

The FS-60 will be 374mm focal length which will still only give a ~5mm sized sun on my chip - but definitely allows for a few solar radii.

Bound to be cloudy after I've invested in a new scope and portable mount, taken time of work, organised flights, hotel and hire car as well as spending spent hours testing software, writing a script and rehearsing...
