That give you 3.5 fish per acre which is not easy. On my water I'm looking at closer to 5.5 fish per acre so still pretty tricky. It's easy enough to go on long blank runs, believe me I've been there.
If you're confident in the rig you caught on, use that imo mate. I would never choose a second rig for the sake of it. I would only ever choose a 2nd rig to suit a specific substrate, spot, or situation. Adapt to the angling situation, and what you can see with your own eyes.
First thing I would do in your situation is adapt to the weed - long chods or variations thereof smashed straight into it on one rod. Still very effective if done right!
