									Well since your penal legions cant take upgrades, that leaves everything par infantry to your sentinels. Regardless I wouldn't take a heavy flamer on a sentinel, I would either go autocannons or lascannons. If you expect lighter armour, especially on the sides then take autocannons. But anything like a landraider pops up, you'd need all of those 6 lascannons to hurt it.
