Less barking, more wagging!
It almost doesn't matter what rounds you put on. You're not used to playing on them, so you're going to generate noise you're not used to hearing. So my advice is something different.
When you put whatever rounds you end up putting on your bass, start practicing with headphones, and make a point of leaving the treble or brightness turned up. You'll hate it, but that's kinda the point. Just keep it up, and slog through the annoying sound. What you'll find is that you can significantly reduce and almost eliminate string noise with improved technique alone. Once you've made the adjustments to your technique, you can put whatever rounds you want on your bass.
True!
