You can run whatever you like depending on how you like it to handle.
You may be a little heavy in the centre and rear, but it all depends on the track, or where you are running. If you are just bashing, which with a .28 I am guessing you are, it will be fine.
At the moment I run 3k, 5k, 2k, on a bumpy clay track that tends to be a bit broken and dry on the surface.
