SO with 6th Edition right around the corner and a new Tau Codex in the next decade.....lol

ahem...

what modes would be safe bets to buy??

I was thinking to play small 500-750 pt games and I'm going to say Fire Warriors for sure and Devil fish....and since that's the case....Hammerheads and or Sky Ray kits so you can have the swap out parts...

What do you all think??
