Okay, I've told you that the rocklet will get you more maxes in a single run than Decis, here is why:
In the SAME SPACE as a spare deci, you can fit 45 rocklet rounds.
45
+6
51
51 total rounds, again, this is only if you are using the same space as a spare deci. How many maxes will that get you?
Well it takes 8 rounds to kill a max, what is 51 divided by 8? :O It's 6.3ish(did it in my head). Anyway, how many MAXes do you need for MAX buster gold? 6. How many maxes will you kill with this loadout? 6!
DO IT!
