many thanks james
You've got things backwards. The current draw of the system is more limited by the ESC and motor than the battery. The C rating of the battery, is what it can handle, and maintain cell health.
More C typically means tougher cells, so that's better in the long run. It also typcially means less voltage sag when you do load up the system.
As long as weight, and size, are not the question, more C is always better.
