Special duration up is best for bomb rushes since they're useful for pushing territory and the amount you paint also goes back into refilling your special gauge.
I use it on my .96 Gal setup. I wear gear with it and special charge up so I can echolocate everyone often and for a longer time.
Ah, I guess it's really just a case of me not using any setups that benefit from it ^.^;
Also does anyone have any general tips for using the inkbrush? I was one of the ones who used it when it launched and sucked big time and never touched it again
* use the swings to spread ink, not the 'run', the rolling method doesn't actually put all that much ink down and is better for manouvering.
* you kill by getting the drop on people and spamming the attack button, unlike rollers where a splash or two or even just running people over suffices. With inkbrush you have to hammer that button like you're trying to do chun-li's lightning legs and make sure you don't overestimate the range: if you don't jump or aim upwards it's pretty darn short

* sprinklers. sprinklers everywhere! (an inkbrush can dominate splatzones in blackbelly park by slapping a sprinkler ontop of the central pillar and just spamming ink slashes in the general direction of the zones so it rains down on them.)
* to expand on the previous point, having a sprinkler painting area while you're painting area elsewhere makes your special fill up nice and fast and gives you a juicy score so whenever you don't have a sprinkler set up you should probably look for an opportunity to toss one somewhere useful.
* in order to get people to not pay attention to you, a sprinkler tossed on an opposite wall is usually enough to distract most people giving you the opportunity to roll up and begin the slashening :3
* don't bother taking people head on with the brush: if someone sees you use your superior rolling speed to escape, go around and flank them. You'll end up behind them before they even realise what you're up to
That's how I play and it works pretty darn well. Anyone is free to expand/correct those points though
