which is best? i wont be doing anything too extreme off road just a few green lanes.
the normal steering guards or these Steering Guard / Steering Bar Protectors & Damper Relocation Kit - £35.00 : Tarantula 4x4, eXtreme Off Road Engineering

up to you

I've got one of them. Basically two oversized tubes. Haven't fitted the rear one as it's to large and just rattles around (you also have to cut the steering damper mount off the track rod). I wouldn't buy one again.
I'd either get the Wizardbilt damper relocating kit that's on Ebay for the same price or if I could afford it I'd get Sumo bars.

Personally I don't rate standard steering guard things as in deep mud or snow the front end can ride up and you loose traction.

I can thoroughly recomend the Wizardbilt damper relocation kit, very simple and works a treat, had mine fitted for about 4 years now.

Used alongside sumo bars gives a really good bit of security, but as I have been driving mine on more and more difficult terrain i've bought one of these
