The ZT profile has been inspired by the highly successful FUBUKI™ a and designed with the better player in mind. This new profile has a stiffer mid-section than the FUBUKI™a, with lower launch and spin than the a yet still higher launch than the K-Series. The ZT profile includes heavier weights, low torque, and a higher balance point to make it optimal for today’s adjustable tour heads. The ZT profile will also feature 40-ton carbon fiber material for outstanding stability.
We do not have any Fubuki 55 graphite shafts in a Senior flex. In looking at Mitsubishi's catalog they never manufactured a Senior flex Fubuki 55 for the aftermarket.

what does 4b1s mean on the Fubuki ZT wood shaft in stiff. my swing speed on the driver is 91
Asked by: Joe
The 4 stands for an S flex shaft which we rate with a swingspeed range of 93 to 107 mph. The B tells us the weight range of the shaft and we use B as a mid weight shaft range. D is for the lightest weight shafts for distance and C for the heaviest weight shafts for control. The 1 tells us it is rated for a low trajectory ball flight, 2 would be medium and 3 for high trajectory shafts. The S tells us this a shaft to help correct a slice. H would help correct a hook and M is not correction needed.
At 91 mph that puts you in the high range of an R flex shaft or in our MPF codes a code that would start with a number 3.
