I need show names for two games pony mares?

ive bought another two ponies to train up, both bay mares, very very fast ponies, i need names for them for gymkhanas where i will start their training. my current ponies names are pocket rocket and gold rush (he's gold coloured) and i want names that will fit in with these, so they must be two word names and relate to them being fast, but i dont like having two ponies with the same names so neither names can have the words 'gold' 'rush' 'pocket' or 'rocket' in them please :) their names are lilly and rosie and lilly is quite dark but not quite dark bay, and rosie is quite light but not quite light or bright bay haha, rosie has a blaze and lilly has a big star, a snip on the end of her nose and a white tiny stripe between them but not touching the star or the snip. i dont want anything which says 'im really really amazing' cause they might be really bad, they havent done games before haha, but i wont change their show names so if they turn out really good then i want the names to still be good if you get what i mean, the names have to basically say 'im fast' lol and not have their stable names in them! :)
