Heres a chart of my size options for the frame:

The 'get a slightly smaller track bike' logic would suggest that I should go for the smallest size since Competive cyclist recommend that I should be riding a 52/53cm road bike.

However I have been riding a 56cm road frame for nearly a year and an even larger one before that. So ive got really really used to the feel of larger frames with super short stems.
