I've played both the Hard Rockin steel rounds and the Deep Talking steel rounds, and I'm not sure if there's any difference aside from available gauges.
They're both fairly mellow compared to most steel rounds.
Here's the stock descriptions for both:
Deep talkin rounds:
La Bella's original formula Round Wound electric bass strings. Deep Talkin' Bass Stainless Steel Round Wounds have a thinner core and use multiple wraps of winding.
Hard Rockin Steels (they're just called stainless steel roundwounds now, but they're the same strings as far as I know)
La Bella Stainless Steel Round Wound Series electric bass strings are bright and long lasting. La Bella Stainless Steel Round Wound Series strings are super flexible, great for bending and sustaining notes.
