I find this assumption offending. How would you feel if someone told you that? If you're accusing me of playing "riffs", what is wrong with playing "riffs?" I try to stay away from playing riffs, but to be honest even the best players have riffs. I asked Mimi Fox about that and she said that definitely everyone has their riffs that they play. So I would say, yes, on the occasion I will play a pre-planned riff. But I pay careful attention to make sure it fits musically into what everyone else is playing, and in the context of the song.
