Grey Knights 500pts?

[Sergeant CJ]

Hey, bought the Zone Mortallis set off Forgeworld a while ago, and was looking to run my GK's in it.
Given it's a pretty close quarters type of playing field, what kind of list would be good?
I Currently run
1 X 5 Terminators, 2 Force sword + 2 Halberd and a Hammer = 200
1 X 10 Strike squad, Psybolt. Combat squaded. = 220
1 X Inquisitor, Rad and Psychostroke, Plasma Syphon.
Thinking about ditching the Psychostroke in favour of better armour for him.
He runs with the Terminators, screwing with any plasma rapid fired their way.

Also considered taking 2 X 5 Strike squads.
and 2 X Purgations, with 4 Incinerators in both squads.

Thoughts and comments?
Even new list suggestions?

Suppose I aught to mention, the main foes have been CSM and Guard, so for all I know, CSM may well change drastically very soon.

Personally I'm trying to squeeze in a few termies and a dread knight with brother captain to make legal army. Also, purifiers with psycannons/incinerators as needs be. And I'm gonna chuck in the paladin upgrade to termites for apothecary and banner. And remember, NEMESIS FALCHIONS AND HALBERDS ALWAYS. Or maybe demon hammers...

I just keep a couple swords for the times they inevitably come across other terminator with fists. So I allocate against the 4++ first
