I love the netting, it's one of those things that sort of makes your suit immediately recognizeable as the Predator. But I can do with or without.
What's the netting for anyway? Most of us here know that it's the circuitry for their camouflage. But how does it work exactly? Does having it on 1 part of the body enough to make the whole Pred invisible? or does it have to be the whole body? P1(yes, the original by SW studios) didn't have the netting on his right arm. Wolf, didn't have it on his legs and his right arm. Unless someone from SW studios comes out with an official 'how the predators suit works' book, I say feel free to improvise.
The Super Predators didn't have any netting, but according to movie lore, they're a much advanced race of Predators, so maybe their 'camouflage' technology is way more advanced than their inferior 'cousins', not using netting. If you notice, their 'cloaking is a lot more effective (i.e. you can't even see it bending light). If I was making a P1 or P2/elder suit, I'd definitely make the suit with. But a custom, I reckon it's all up to you.
In Broken Tusk/Dachande's world, they call it a 'Shift suit' in AVP Prey, and depending on the hunt, they choose to or not to wear the shift suit, as with xenomorphs/bugs, Shift suits won't do them any good anyway, especially to a creature without eyes.
I know I might be labeled as a blasphemer, but with the custom i'm making, I'm 99% sure I won't be using netting because 1) my Yautja will be covered with tattoos and 2) his backstory will be he's coming from an island/tribal sort of location, who don't hunt/kill while 'cloaked', they use their natural surroundings and skill to sneak up to their prey, therefor, they have no use, and refuse to use a cloaking device. ;P
I've read It's actually in their code to not kill prey while cloaked, or it's considered less honourable for them to kill from afar with shoulder canons, while cloaked, especially when they're on a hunt. 'Clean-up' mission done by Wolf was different. Or 'survival mode'. Use every arsenal to get the job done.
