Reading John P's post I realise that I also do a far wider range of rhythms than I mentioned above. Without my guitar to hand it was hard to visualize (rhythymualize?) them.

I think John P's suggestions are a good place to start and would say, as a general rule, that more or less anything goes as long as it:

- doesn't detract from the melody of the tune - is interesting and has variety - is interesting for the player
