Outer Limits 4x4 Board

hi i was just wondering if drop shackles are legal in NSW and what experiences people have had with them thinking about getting them rather than extended shackles

i hate being a nazi but:

I'm running the climax drop shackles on the back of my zook, with inboarded rancho 9000's, and havent had any problems what so ever with them. A-lot of people dislike them due to various reasons, but personaly speaking i think there a good thing.
