Yeah the Pretoria's in silver would be my pick (I've got them in black, on my Wolfsburg). I bought some 'light weight' wheels for track days, which are actually heavier than the Pretorias! They are an awesome wheel!

On topic of the 40th versus R thing - I've owned a MK6 GTI (modified), and obviously the 7R above (which is also modified). The nimbleness of the GTI is the key here. The R is definitely sure-footed, but it feels weighty compared to the more 'chuckable' GTI. The clubsport/40th would be another league again with its tighter suspension and other bits.
That said, I disagree about traction not being an issue with the 40th anniversary. If you're keeping the car stock it might be fine, but if you're modifying at all, you WILL have traction issues. The LSD is great for corner exits, but you're going to be breaking traction in slower corners with BOTH wheels (LSD is irrelevant here!) when you increase the torque with an ECU tune or similar. By comparison in the R, often you can mash the throttle before the apex and it will just pull you tighter into the corner and lay down 100% torque on corner exit. That is massively confidence inspiring, and I find myself actually pushing a lot harder in the R, where I would be much more tentative in the GTI. Personally I enjoy being able to push harder (read: faster) in the R, over the fact that the GTI was more nimble. That's just my personal preference and driving style. It's really your own style which will decide which is more enjoyable to you.
As someone else mentioned, test driving a PP will be similar in feel to the 40th. Though I doubt you'll be pushing hard enough in a test drive to show the true differences between the 40th and the R. Good luck with the choice though mate - they are both killer cars! :)
