Personally, I'd start by stacking a bunch of swim speed and then some run speed. I like about 2 swims for every run (since I understand they nerfed run a little). You could also make room for some special charge up or some extra ink, depending on your play style. For turf and possibly splat zone, consider last ditch effort. It only works in the last 30 seconds, but if you look at how much ink you get in that time, it's kind of crazy. For turf, in most battles, the last 30 seconds really decides it.
