Aerospray PG - Great kit, just not for the Aero. Damage up caps for the Aerospray at only 1 sub. 2 subs of damage let you kill with a direct and indirect burst bomb hit, but really you aren't able to apply damage and pressure from far away like other weapons. Kraken is great, but doesn't help with the issue of range. IMO, this set doesn't fit the weapon as well as others. Neo Splash does burst bombs better and has a long range special, while there are multiple other weapons with Kraken that are similar to the Aerospray.
Cherry H-3 Nozzlenose - An amazing set, completely outclasses the other H3 sets. Gives you amazing defence and amazing offense with walls. Bubbler doesn't require much meter to get. The only problem this weapon has is turfing, but other teammates can fill that gap.
N-ZAP '83 - Amazing set, rivals the other nzaps, but they really all have a unique niche for what roles they play on the team. Comes down to preference. But I do think this set outclasses the neo sploosh.
Grim Range Blaster - The custom range blaster has the perfect kit. Sure this kit is great, if you like using damage up great, but really stick to the custom or try the rapid blaster deco for wails.
Sploosh-O-Matic 7 - Outclasses other splooshes. Great variety depending on your play style. On par with the octo n really comes down to whether you like to use brushes or shooters.
CoroCoro Splat Roller - Will have to try this one out. On paper it looks odd..but I can definitely see it working using the walls aggressively the same way the 52 does but with a more offensive special. Good variety compared to the other splat rollers and again comes down t preference.
Bento Splat(terscope) Charger - Interesting, for those offensive chargers. I think this will really only work for the scopeless version, with lots of damage and run speed.
Heavy Splatling Remix - This baby should pump out a lot of killer wails, if that's your thing, then great. Not much of a splatling user so not sure, but seems as if the other heavy splatlings are better at dealing with the weaknesses against short range foes.
