The Blur (60g) in the R11 is well known to be a pretty poor shaft, and is a shaft made for TM and somewhat different from the 'real' Blur. If you get the R11 TP, you will get the 'real' Blur, which is better but still not fantastic.
The Fubuki in the Mizuno is a 'made for' shaft, but is very close to the original, which in any case is a lot better starting point than the Blur, and is basically just optimised for the Mizuno. You can buy one of those with confidence.
I believe the RIP in the Titleist is a real shaft, but if not, it is pretty close to the real one. The Project X in the Titleist is definitely a 'real' one, and is a strong shaft that many average golfers have struggled to hit well because it is pretty stiff and unforgiving. The Diamanas in the Titleists (apart from custom upgrade versions) are 'made for' and are a bit weaker than the 'real' ones. The price point of these is not a very reliable guide to quality or provenance.
