I bought these strings to put on my basses after around 10 years without playing. 
I did'nt wanted to buy some more expensive, without knowing if I would come back to bass playing. Also, I wanted to try some other gauges, so, the WW Red were a good choice. 
 
They sound really bright in the trebles, but also in the basses. 
I used Rotosound and GHS in the past, but I think right now, the WW are a good choice and far cheaper than the mentionned brands. 
 
Last but not least... their lifetime is incredible! More than a year after mounting the strings, they still sound bright, and with very little cleaning from time to time. Even the detune over the time is very little.
