Double Happiness G777 how like? Stick do? How the price difference and the 666 so much ah? Viscosity

729-2 used, it can be compared, and still love how the bursting of Bo like?

---

g777 is relatively soft, the viscosity may be older than 666

666 is more nearly 729-2 classic

the new 729-2 with readings higher hardness a bit astringent some plastic surface is not very sticky ball a little faster

old 729-2 corresponding relatively less force

729-2 is not sticky, not as a comprehensive CJ8000 Type
