Hi, sorry I didn't give you credit for the photo!
Well spotted by the way, and this along with throat specs on opposite red/black; either shows that Federer had very early different version of the retail BLX90 as a hairpin for his racquets this year. Or more likely, I reckon it is a retail/custom K90 under that BLX paintjob.
However, whatever these specs show, we will never know for sure until someone cuts up one of Federer's racquets to compare to retail racquet, and I don't think that will ever happen. So effectively it will remain a mystery and just be speculation!
