Outer Limits 4x4 Board

I am after some advise on the radius arm bushes on the chassis end....What are people using in the winch challenge trucks etc for bushes and how long are they lasting?? I recently completed an event and i went through a set of bushes in 2 days??

What's the best type for durability wise??

Do people run a different style end on get away from the bush

Any opinions would be great.

Thanks
