Firstly, HIGH FIVE !!!!

ok on to the tactics.
i run 2 squads of 5 both loaded out differently, i find they both work well.
the first squad has - 2 pairs of lightning claws, 1 chainfist, 1 hammer, 1 powersword, 1 heavy flamer, 2 combiflamers. - these guys are really good for killing anything with 3+ or lower armour.
the second squad has - 1 pair of claws, 2 hammers, 1 chainfist, 1 power weapon (havent decided which yet), 1 plasma claster, 3 combi plasmas - they kill everything extremely well.
so i guess if you want to be good at killing anything you could maybe go with this:
4 pairs of claws
4 hammers and combi
plas
2 chainfists with plasma blasters
????
that would kill anything reliably, especially coming out of a storm eagle.
hope this helps
