There's going to be a lot of T4 with crap saves. Large blasts with high strength and almost any AP value are gold. If he's loading up in trukks, they'll be fast assault vehicles but AV10 and open topped. It's just he can bring so many. He can also bring bikes. Ork shooting is crap. If you can stay out of assault range and bear down a bunch of firepower on him, it'll work wonders. Most ork hordes aren't going to get saves against bolters, but with their toughness and numbers those wounds may not be enough.
If I was to run White Scars against them, I'd forget special weapons all together and run mass bikes. I'd take as many missiles as I could. The krak can stop his kans and trukks, the frag can hit his hordes. I'd forget about flyers all together because I doubt he'd bring enough to do any real damage. I'd also bring as many large blasts as I could fit. Whirlwinds, Vindicators, Thunderfires and even the deathwind on a drop pod.
I definitely wouldn't take a redeemer. He can CC that thing to death and it'll only kill like 10 models. Close combat isn't going to be good for you. Just max out mobile ranged firepower or long range table edge firepower and you should do okay. If you can keep them to just shooting you'll outshoot them all day. Just watch out for skorchas. They can bring like 9 flamers for cheap and their BS2 won't be a factor anymore.
