Even Mr Fikus reckons it is expensive...
At the end of the day, the Big 7 is an excellent circuit (world class whatever that means, but it obviously is rated incredibly highly by the majority who have witnessed one) with foo parts exactly where Lukasz said they were needed, and non-foo where he said they weren't. I think he has basically made the GG for those that didn't believe this and asked for extra foo. He knew he could sell them and who can blame him for doing so.
In my opinion he was right the first time. The extra foo may add a little more to the performance but it doesn't amount to a big difference. Diminishing returns, I think, must set in really heavily after the B7 Lite point.
I'd put my money on the B7 Lite being super seriously good VFM compared to a GG, and pretty good compared to a B7.
