you should seriously consider becoming a salesperson mate! haha i'll check if the pro s coils are also damper adjustable because i guess that would be a major benifit to me if i want a comfy ride, i could just make them less stiff. i get what you mean too mna, i suppose buying a combination of brands won't be as reliable as getting the same brand in one unit. i'll see how much i can get the pro s coils for and decide from there. thanks a lot for your help mate, much appreciated
