You gotta go 220 s_and_m for three reasons...
1: A Works has 210, so you MUST have more
2: The cold ram induction system makes a truly awesome noise when you cane it
3: A Works has 210, so you MUST have more
Seriously though, the cold ram is well worth the extra pennies - MINIs are not all that good at dealing with hot air so get anything that can help. In hindsight, I wish I'd gone for the GTT intercooler (230 package).
The re-route pipe is a great compromise if you want a bit more burble but not too much noise, especially if you do a big mileage and need to keep some refinement. I do about 20T a year as well and took all this into account when settling on the 220.
