Somewhat stupid question about Sunrider

[Kokopelli]

Apologies if the answer lies on the surface.
I've been digging through FLStat and testing various ships in SP when I noticed this civilian VHF has some pretty good stats, at least on paper. It has decent HF-level armor + high powercore but is also FAR more agile than most LFs.
How come people don't abuse the hell out of it when you can fly circles around the enemy like a LF and rain fire with your energy-efficient Class 8 guns? I can't remember seeing other players fly it. Does this have something to do with tech compatibility or its hitbox (which is quite big)?
I really must be missing something.
