I general I agree with Frank here:

But I can see this point, if there is something to be recognised in the issue:

[quote=xr200;188533]For example, I would not use the typical bike helmet holder on many modern bikes to "secure" a helmet, especially an expensive looking version that looks "attractive"; and certainly not by the fabric strap of the helmet.
A stanley (box cutter) knife will remove the helmet from the bike in a flash (I mean slash of course!)*. The thief is not bothered that the helmet does not have a strap thereafter.
If you can "think" like a thief - for instance, not overly concerned about damage to the bike etc - then you will probably be on the right lines in arriving at the methods that work for you.
A temptation is to cut corners in using security devices and procedures; you have to get it right time after time, the thief has to get lucky only once -thieves always have the initiative in what they do next.

Peters' references are of interest: Gatogato is getting a series of lessons in life that may stand him in good stead for the future, assuming that he remembers and learns from them!

* This has happened in Mediterranean countries from my discussions with other riders.

Soft luggage: I have used it a few times around Europe - I always carry away with me the tank bag; this contains everything of value to me, including things like paperwork.
My attitude to the soft panniers is that they are "dispensible": I won't like having them stolen but I could get by until getting replacements of the panniers and the bits inside. However, there are loads of other threads about looking after soft panniers including, for example, carrying them into visitor centres and the like wherever you stop.
