I have a VC200L on an EQ6 with a 127mm refractor as a secondary imager/guide scope. It handles it well. I have a reducer but rarely use it.
Not sure about an HEQ5 though to carry 2 scopes.
f ratio is totally unimportant for visual as you vary the magnification with your eyepiece fl. The only difference is that a longer fl eyepiece will achieve the same mag if the f ration is bigger. 8mm eyepieces seem easier to use than 4mm one etc.
Lots of people comment about the spider but for deep sky it is not noticable at all. For planets the VC200L isn't optimised. It is a very well corrected astrograph with a flat field to the edge of a 35mm film frame.
I can't comment on the SCT scopes except that I someimes use our clubs 14".
It has much better light grab but dew is a real hassle- something that rarely affects the VC200L
