Boys before toys is indeed dead. Since the new book came out, I've never run a boyz unit without 'eavy armor. Add in a painboy and a warboss with a lucky stick (gives the whole unit WS5) and you've got a unit that will march right up the field laughing off thunderfires, wyverns and almost everything else as well. back them up with 1-2 units of 'eavy armored shootaboys as they move up. Warbikes are IMO the best unit in the book. The FW special character Zhadsnark allowed bikes to be troops and his rules are free to d/l from the forgeworld website. Don't be afraid of allies either, to make up some of the Ork's shortcomings. I've ran Tau, but mostly CSM. A nurgle bike chaos lord, with 5 nurgle spawn is a great complement to 15 warbikes with warboss and painboy on bikes. Shooty orks are great, but lootas now fight with mek guns for HS slots. Mek guns are amazing. the S8 plasma cannon will send marines running for cover, tracktor kannons to pull down those pesky flyrants and lobbas are still good against just about everything.
wierdboys are not bad, as long as you use them to summon deamons. The Ork powers are...lacking. First summon should be pink horrors so that that unit can summon up other stuff. Deamonettes are my favorite as a complement to a CC ork army.
