I think it all comes to the result you expect.
Do you want to perform on the tournament at all cost? Does your team expect an easy list to handle for the pairing?
=> Go for the common list they already prove what they could/could not do.
Do you want to have fun mainly?
=> Try anything you want, you might do better then expected (you could also regret it, but hell, is that not worth a try?).
Goes to show that maybe we just need to find a combination outside the "norm" to make an army rock. Something the opponent is just not ready for and I believe someone already found something funny using 2x6 wretched ones. I'm curious is we just don't see a combination just like that. Of course, getting more bang for our buck would be great first as we pay top-dollar right now.
