well we always 'start afresh' and move to the next track when we've done a track. i really hate going back onto summit .... but do what you feel is necessary.
i think i'd love to hear some of your stuff on CD to get a better reaction. it's hard to comment really properly on computer speakers, but i do think you should experiment with some more 'loops' in your style. create your own or buy a cool sample cd and add them to your sound. i think you'll be really surprised....
