When to use which

The bigger scale has more colour and more ways to go wrong; the smaller one is safer and plainer. Start solos in the smaller scale and add the extra notes as a passing tone, on the way to a note that belongs to the chord. Live on the extra note and it stops sounding like colour and starts sounding like a mistake.
