Knights vs Dread Mob

What is the best way to celebrate Labor Day? 150 Power Level kill-fest with giant robots of course!

We took my newly completed Terryn Knight Household against a Scary Ork Stompa-Dread Mob. Four Turns of Mayhem resulted.
I just finished up a Knight Castellan and three Armigers, but I had to go back and do some touch ups on my four previous Knights so they would match up. Which entailed re-doing all the gold trim and rebasing them. Yeah, I know I'm a bit crazy. But now they look like a unified force.
The Ork force was led by a Stompa (with the Gaze of Gork) a Gorkanaut, a Mega-Dread, and a host of Dreads and Kans.

Both sides charged straight at each other, firing all the way. The Knights shooting was overwhelming, and was able to thin out the Mob before it closed to melee. The close combat was as fast and brutal as you may think. The Stompa took out a undamaged Paladin with it's Mega-choppa (24 points of damage!) before the Knight Baron fished the Stompa off with a spectacular 20 point hit from his Thermal Cannon. The Knights took a lot of damage, but only lost one Knight and all three Armigers.

 
It was a good game, but I do feel the Knights might be under-pointed. More likely, the Orks (who don't have a real Codex yet) are too expensive. Of course the lower end units, the Kans and Dreads probably knocked the Ork side a bit out of whack.

I would like to run this battle again and give the Orks a 51 PL handicap, which happens to be the price of a second Kustom Stompa...
