Steel Rotos are my favourite strings. I play in an alternative metal band in which I have the freedom to use different techniques - slap, tapping, etc.
Since I've had hand issues in the past, I tend to stick to lighter gauges. The tone is great, though it might not be for everyone's taste. It is bright and it has a lot of mids that help the bass cut through the mix. Also, it stays bright much longer than some of other brands that I've tried, like D'Addario and Ernie Ball. Another thing that I like about Rotosounds is their reliability and consistency. I have been stringing all my basses with this brand for the past 10 years. Yet, I have broken
only 2 or 3 strings. Bear in mind that this happened on my practice basses after months of heavy use.
If you are into alternative music and in need of strings which will give your instrument a more agressive sound, I highly recommend Rotosounds! However, I don't believe that these will work with some music styles where the bass stays almost always in the background, so keep that in mind.
