well the jesters are obviously the better binding, but for most park skiers the Griffons will do just fine and are cheaper. I'm switching to the Griffons on my park setup this year to save some money.
At 6'2 190lb I wouldn't trust Griffons on my 195 pow sticks tho.
If your a 5'6 130lb 16 year old the jester pro is probably going to break your knee off.
