I have been playing around with some shoulder units for my NEXT.

Let me first state my next is an offensive missile type. Left back unit is a large missile and right back unit is a fast missile. Both arms right now are chain guns. Its has good AC at like 3700 area and average speed.

Now the shoulder unit I currently have is a scatter missile(I think thats what you call it). It gets 120 magazines but the only problem is it can only fire two at once and I can only fire it when I fire a back unit missile so I don't feel like im utilizing it to it's fullest potential. The other option is the shoulder unit that fires a cluster **** of missiles but I only get like 3 shots with it.

I might be able to unlock some more stuff since Im not done unlocking everything yet, but you do you guys recommend as far as a shoulder unit goes for a NEXT like mine.
