People on here love the durability of the STH 16 and STH 14 driver. I have no idea how much it weighs though...
I have Jesters on my Bacons, so not a park ski, but they are doing really well, and are much lighter than the PX12s on my invaders. They feel WAY lighter. The Griffon is even lighter but has more plastic in it so lots of people shy away from them for that reason. I haven't heard of many people actually breaking theirs though...
