I thought people knew most of those combos, anyways i cant beleive you can pb frc 2s 2hs heat chipp of all people to much damage on him mid screen. basicly with chip one buster and its game over unless hes at full health.
I guess ill share some of the combos i been using
hammerfall frc c.s f.s tk buster (need to be close enough)
dust combo jh,jh,jk,js,jp,jk tk buster (simple dust combo does about 40-45%)(depending on some chars hitboxes it will take 2 jp's wich lowers the dmg very minimal)
for a over head combo i like to 6k 2h hfb jp,jk tk buster if you land in the corner on some chars (the only ones that come to mind is chipp venom and eddie im sure there are a few more just cant think of em and havent tried every char) you can 5s 2h heat or if you land in corner you can procede to air buster loop with c.s f.s tk buster does heavy damage.(edit i forgot to mention that the air buster loops work on all chars not just the mentioned ones)
theres more these are just at the top of my head.
