Great first run on a tactica Azonalanthious! Well I know you didn't mean it to be a tactica, but with the tiniest bit of legwork you have one right here, which would not only garner teef for the WotW, its something that the greater 40kcommunity of the Article board needs!
If you are interested in upgrading this to a full tactica I suggest taking any and all input you get here and improve the article for a posting in the Ork Article board (which I believe as a minimum post count as to access it). Once on the Article board editors and other Article workers work with you to improve the article before you submit it to the Article Board itself, where it will shine in the halls of 40konline, and possibly get on the front page of the Forum.
All that aside, I too must admit that for years I was using an M styled formation with my Bikers, but the Oval is superior! Thanks for the advice Az
Peace
