TC3 fits for Worm hole ratting c4 c5

Was just curious if there is a groups of dudes out there that run TC3 aka legion, tengu etc for combat sites in a c4/c5 worm hole if you would post your fit i’d apprecate it.

I think groups of them can clear C4 sites. But whywouldnt you just buy a Nestor/Leshak gang for the same ISK and clear them faster?
