WillowsJesters are reinforced with metal whereas griffons are not. Griffons are lighter but also a bit less durable. The main difference is the DIN
Griffons go to 13 i believe
Jesters go to 16
Jester pro goes to 18
parkskier5Griffons can be found for way cheaper than jesters, so if you don't need the higher din or extra durability, go for those. I've been using griffons all year and have had no issues.
