So in our local 2k tourny in November I'm taking Knights, the list is .....

1 Knight crusader with....battle cannon, gattling cannon, Heavy stubber, twin icarus cannons

1 Knight Errant with-Thermal cannon, Reaper chainsward, heavy stubber.

1 Knight Gallant with-Reaper chainsword, Thunderstrike gauntlet, heavy stubber, stormspear rocket pod.

1 Knight Palladin with- Battle cannon, Reaper chainsword, heavy stubber.

1 Knight Warden with-Gattling cannon, heavy stubber, Thunderstrike gauntlet, stormspear rocket pod.

My main question is, what formation to use? Do I give them the battle save to a 3+ or give them all the better BS to BS5 and the king BS6?
