These things have a thousand and one uses, so get them all under your fingers. Here they are over two octaves, and starting from each note in the scale. My earlier posting about pentatonic scales will show you why some of the starting notes sound better than others and when you might want to use one over the other.
Having these together means you can solo over anything, maybe it won't be the snazziest solo ever, but you will have some note choices that will never fail and can be used in any style of music.
