i have tried it all. trust me when i say this. it does not matter what you use because if someone wants it they will find a way to get it. i have stopped locking anything. not even my cameras because it is just a waste of time and money. locks are only for honest people. so if an honest person finds my stuff they aint gonna take it wether it is locked or not and if someone finds it and wants it they are going to take it wether it is locked or not. best you can hope for is they get discouraged or you catch them. best of luck
