I mostly use the ned for smallmouth. It tends to get hung up in weeds when I’m in largemouth territory because it has the exposed hook. There is a version called the Tiny Child Rig but I’ve never used it. I’d rather just switch to a texas rig instead, personally.
As far as the jig heads, use as lightweight as you can so that it still sinks to the bottom given the current, depth, and waves. You may have to adjust that. There are a lot of plastics you can use too. I like the zman elaztech because its naturally buyoant and very durable.
There are a lot of brands of mushroom head jigs too. I like the VMC ones. The only ones I would advise not using are the original zmans. The hooks are very light wire and they will bend easily.
The other thing is with the ned, I tend to catch smaller fish on average with it because of its small profile. It can be a dink magnet. It will still catch bigger fish, but it just catches a lot of small ones too.
