There is something in CORTech that causes the puck to act like Flubber when it rebounds. I wouldn't be surprised if the Bauer labs re-created Flubber, and used it as the coating for their pads. I'm rolling on the floor laughing just thinking about that.
At the same time, the Primo on Brian's pads makes them as slippery on ice as a greased pig. The ultimate butterfly pad would feature a combination of Primo on the sliding surfaces and the Flubber-esque hard rebounds of CorTech.
Anyway, I agree with you that no major changes does not make it worth my time to drop US $3,000 on a new set of pads and gloves. Especially when I don't have $3,000 in the first place.
