Hi Graig,
When I got new shocks for my old girl I could only get hydraulic shocks from Mr Pedder. They are a Black shock and are classed as heavy duty. I have found them to be really good and they were not expensive. I had the same trouble as you in trying to find a comfortable shock.

PS when you took a picture of my old girl on sunday, did you use a digital camera
If so could you email a copy to me as I dont have a digital camera and would like to save it as picture for my pc, Thanks
