Now I know there's no full-proof theft-free system for bikes or saddles. While most shops have mentioned one way to avoid saddle theft, though, is to carry a chain (or cable) to loop through your saddle.
But I would assume that would make one no more susceptible to saddle theft than a cable lock for a bike (ie. 20 seconds to cut through). And after all, how does a saddle thief steal a saddle? Don't they just carry a hex-key with them and remove/loosen the bolts (after cutting the cable-lock if there actually is one)?
So wouldn't security bolts be the best solution? I mean, a bike thief or saddle thief is looking for a quick easy theft. They're statistically less likely to steal the bike with two locks then the bike with one. More hassle. More chance of getting caught.
In the same way, wouldn't they be less likely to steal the saddle if they don't have the tool to remove the bolts?
Check out these bolts as an example:
