If I understand you correctly, you're using hose with threads on each end, not the Macro/Micro line that are just cut lengths of plastic hose. If that's true, then either hose will work well for you, but the steel braid tends to look slightly more "pretty" and is slightly more abrasion resistant.
If you play tournaments, I'd recommend steel braid hose. If all you play is walkon, then the black hose is fine, but for a few buck more...
good luck.
