Sorry if this has already been hashed out-- I searched the forums but couldn't find a recent thread about it...

I just built up a steel frame bike that I now love, possibly more than my beloved wife. I joined the Brooks saddle crowd as well, and am thrilled with it. I plan on using the 'Sheldon' mini-U method, and using Pitlock wheel skewers, headset, and seatpost locks to protect the main components.

The remaining problem is the saddle clamp on the seatpost. I know about the cable loop that Pitlock sells, but that seems too easy to lop off. Using the bikechain/tube combo is insanely popular, but that again seems too easy using a chainbreaker. BB's/superglue or solder in the allen recess seems like it should be effective, but I'm still at a point where I'm fiddling with my saddle a lot right now, and it would be really inconvenient (I don't think wax would be a good enough deterrent).

I was starting to think that no good solution was available for my present situation until I happened on a picture from the Pinhead website. They apparently make a clamp (only in the 'parts' section, and sold separately from the kits) that you attach around your seatpost right up underneath the saddle clamp, and secure with a locking skewer. Assuming your saddle clamp uses vertical bolt/s near the seatpost body, this would prevent anyone from being able to fit an allen key into them without loosening the locked clamp and sliding it down. My plan at this point is to use that Pinhead clamp with an extra Pitlock seatpost skewer (might have to make an insert or something to get the clamp surfaces right).

What do you guys think? I know someone could still just saw through the seatpost, but at that rate they could just saw through the seatstays or downtube if I used a cable (plus they would still have to defeat the pitlock at a later time to remove the saddle from the seatpost fragment). Any ideas/comments on whether this could be defeated in a way I'm not thinking of?

For the record, this is my commuter, and will be protected most of the time at home and at work. I'm mainly trying to sure up the off times when I've stopped somewhere on the way to/from (in the Northern VA area). Thanks for any suggestions/ideas!
