Are they very different? SPPP seems to be a great string overall, plus it's much cheaper than other quality strings. SPPP Pure is said to be a ad softer but doesn't hold tension as well. Is that true? Also, do they play similar? I'm thinking about trying SPPP( along with Lux TIMO ) but the orange won't look good on my racquets. So the Pure would be my choice, unless it plays very differently. TIA.
