How to tackle a super (with solo HIC)?

Hi there!
So, how you would normally tackle a super in a lowsec (no bubbles) with a HIC?
Never done this before, but my idea is to use capstable 100mn Broadsword - it looks like fighters shouldn’t damage it because sig and speed values (135-150m sig and 600-900m/s orbiting speed).
It’s good on paper, but several times I was wrecked by Nyx with surprisingly good damage application from Cyclops.
Anyone tried similar apporach?
Please, share your experience!
Thank you!
