well i guess that would depend then on whether you play competitively or not..
that's like saying you wouldn't spend $45 extra on a motorized hopper
in many games, a shot dropping off by a few inches because of the noticeable change in fps could mean a big difference between taking out 1 person on another team and not taking them out
each player makes a big difference, in my opinion nitro would probably be either the #2 or #3 upgrade on my list
1st would be a new barrel then either nitro or a motorized hopper
