many seatposts have a bottom clamp whose full width contacts the saddle but with two narrow upper clamps (1). The result being a scissor type action which I've read is a no-no for carbon railed saddled.
Is there an after market top piece that will support a wider part of the rail? The best top clamps I've found is again posted below. Is there another option e.g. using a semi-circular alloy tube to cover the rail? (3)
Also re. the cylindrical top clamps as in (1) - they are thinner hence look weaker than the wider ones (3) - should I be worried about them failing?
Examples of each are below
1, narrow top clamps
2. wide top clamp, much more support for rails.
3. wider top clamps
carbon saddle rails and clamps

I've been running this type of clamp across several bikes (road/mtb), carbon-railed saddles and seatposts and nothing bad happened at all. A lot of other member do the same too.

Berk's seatpost will probably have one (see this post, towards the end), Jure also makes a similar custom top-clamp.
