I would always add the power fist into the grey hunter packs. Expensive but a total of 5 power fist attacks charging and re rolling ones gives then somethiung of a cutting edge. I would consider dropping a few grey hunters to do this and try and bump up the numbers of Long fangs.
It would probabaly be worth considering a squad of scouts by dropping the landspeeder. They will muck up your opponent's deployment plans more than anything and having used them alot they are very much worth it.
