Jock, DeCarbons are Monotube, I have had mine on for almost 7 years now, and they feel the same as when I fitted them. As you know they have been used quite extensively, and they are the reason I recommend them to customers so highly. I agree about the damage possibility, but a simple stone shield would be easy to construct. (Some OME shocks have a stone shield optional ,available seperately, and they are twin tube.)
Don't go for lesser shocks, you will be dissapointed.
