Suspension upgrade, what would you recommend???

I'm looking at replacing my suspension as it is 18yrs old and getting a little tired. I'm not one for serious off-roading but would like to do some green lanes etc. However, the vehicle is mainly a Tow Vehicle and as such would like a kit that best suits my needs. Any suggestions on which brands and kits????
(I would like to retain some element of comfort so nothing too stiff).

Thanks.

Just before you get a grilling have a search about the forums, theres plenty of wisdom out there. Are you thinking of lifting it?

standard height, either standard compression or heavy duty depending on loading/ammount of towing you do, i think standard suspention is pretty good as is for all round use

90? 110? 130?

With self leveller or without?
