Fast n Slow marines for 1st 6th ed tournament

Tomorrow is my first 6th ed tournament and I've decided to break out the Novamarines. It's 1500 points so many have opted not to take any allies, as have I. Psydefense is a problem, but I think this is an ok list. It's also simple enough that I can hopefully finish games on time, as I can focus on playing and remembering a little less new rules.

A couple of swaps. I've ditched the relic blade, going for a power axe instead on the captain. I decided to take a missile for the scouts instead of buying a fist for him. I've also taken meltabombs on the biker sergeants and captain, 'cause they are way better in 6th. Meltaguns got swapped for plasmaguns to better deal with 2+ saves. I think I still have enough melta for 1500 points (2 multimeltas and 3 meltabombs).
