Your road bike might matter, if it's one that doesn't have rack bosses.
I was looking at the Blackburn's as well, if I didn't get a "system". They look like a quality product.
I did go out and check my bike before starting my search to see if it had the standard connections, or at least versions of them, and it does. So yes, in reality it does matter, but hopefully I've checked what really mattered.
