dont put in the points cost(your not allowed copyright and stuff) why would you give your boss a big shoota...
i assume you got the 2 times the same troop??? ok well take one(they will be almost unbreakeble due mop size and the enemy will not like 30 orks

)
now you got some points left
now maybe give your slugga mob burna's i
cc they are power weapons and 3 burna templates before you charge a squad is fun(remember you have to choose every turn if you use it as a
cc or template)
you can give your nob a powerclaw and a choppa/slugga
and... give your warboss mega armour+a wartruk with rockit launcha
now you have spen 445points
throw in a grot mob (15grots+slaver)
or if you play combat patrol put in a killerkan with armour plates and a 5points upgrade.....
i think it fits with what you already got and maybe you like to play like that
---hope i helped you---
