From a competitive player, in my opinion and others in the community, really there are very few weapons who need ink management. ISM is still useful on brella and explosher, some people use 2 subs of ISM on slosher for some extra sloshes. As for Ink Recovery (and Ink Saver Sub) these are very common on weapons with Ink Armor and more importantly, lethal bombs. Kensa Undercover Brella and H3 Nozzlenose D are good examples of this. In this case, main saver is unnecessary on the weapon, but being able to throw out those lethal bombs is huge (especially with the torpedos the kunder has).
Of course, this is at high level play where you want to optimize everything, so you can still apply these concepts to other weapons you like to play and consider what abilities you need. One thing I
will say is to encourage you to try and not use ink management abilities on everything, especially when you don't even need them and can get by without. You said you like to play "ink hungry weapons like pro, dualies, and brush." I could understand pro taking up good chunks of ink, but it's still possible to get by without any ink management. The most common ability you see on pro's these days is stacks and stacks of Main Power Up so you can get 99.9 damage in 2 hits instead of the usual 42 or whatever per shot. Of course, running so much MPU leaves people with no room for abilities like ISM, so the just work without it. How? Practice aim so you take less shots, and only shoot when you need to. Don't just hold ZR and go for it. Same goes for dualies and brushes. People don't use ink management on these weapons because they have other gear they wanna use since they can work perfectly fine without the ink management.
To be honest I would recommend focusing on movement abilities and special abilities over anything else. Mostly movement especially with weapons like the brush, having swim speed will be very very helpful, and most use ninja squid along with that to be sneaky and fast.
Just as some exposure to high level gear sets, I'll leave 2 of my aggro builds (I'm actually a charger main but I can flex other weapons and have builds for them). Take them with a grain of salt since they may not be optimal at every level of play (though stealth jump is still really good).
Build 1
Build 2 (Ninja Squid)
If you happen to have any questions on any of the abilities I'll explain but still for you I would try to focus more on Swim Speed and such. Of course, you can use whatever you want and I have no control over what you use so it's really up to you. If after this you still feel you need ink management then go for it no one will judge you if that's what helps you do better. Hope I could help somewhat!
