Hello all, and thank you in advance for any advice. In the coming month, I'll be entering my first real tournament with a friend of mine and I thought I should run my half of the list by you guys. My friend will be playing Crons tweaked for mowing down light infantry, and I'm going to be the can opener. This is what I've got so far.

Warboss - Big Choppa, Attack Squig, Cybork Body - 90 pts

10 Burnas - 2 Meks - 150 pts

30 Boyz - 3 Rokkits, Nob, PK, Bosspole - 250 pts

10 Boyz - 'Ard Boyz, Nob, PK, Bosspole, Trukk, RPJ, Grot Riggers, Armour Plates - 195

10 Boyz - Shootas, Big Shoota - 65 pts

Fast Attack
2 Deffcoptas - 2 TL Rokkits, Buzzsaw -115

Heavy Support
Looted Wagon - Boomgun, 'Ard Case, Armour Plates, RPJ, Grot Riggers - 135

Note that with the tournament rules I've used up all my options, save for a shared pool of options that has one fast, one elite, or one heavy support. My main concerns are which unit the Warboss should go with and a general lack of plans. Our only main strategy so far is a Cron gun line, Wraiths to tie up heavy weapons until I can get there, and me slicing up armour and claiming objectives. Any further ideas and help are greatly appreciated.
