What to do after 145?

How about snatch? I have a feeling demo has become quite abit of useless even at bosses, since we always dance (well at least thats for me)to be invincible and i feel that max barrage + max ds combo while dancing outdamage demo periodically, although the time taken for the combo is slower by abit. Why not start on snatch so that when the kms update comes, we could snatch and ds for better damage?

Feasible?
