When training on your own I think it is worthwhile training a structured selection of variations; with the point of keeping your vocabulary as large as possible. This is only relevant for movements that you are already executing cleanly in the roda.
As an example of my own - here is a vocabulary of movements that I need to refresh frequently to keep the base of vocabulary increasing in speed and fluency. Of course the list is of names that I call things - so you will have to create your own!
My aim is to increase the speed, balance and execution of my select base, so that I do not lose vocab when under pressure in the roda.
