The test of a handle is not whether it can substitute for the SC. If we have a short valid way to express the SC we should use it instead of the SC. Other short versions are dangerous because they get people relying on them and not reading the SC. (We will visit this problem on the Quicktips - but they are not meant to be short versions of the SC but short easy to understand list of things that are compatible with the SC but not the same. Usually they are more restrictive than the SC, often they are technology specific. But they are useful because they are simple and easy to understand. If you do them get cover most or all of the SC but they may remove options in order to be simple.
Below is a list of the handles. The test is whether you can find an SC from looking at the handles (or remember it basically, but not necessarily remember what it actually says). So think of an SC and see if you can tell which one of the items below it is. It should have good scent (that is - there should be only one item below that matches the SC you have in mind.).
