IMHO, you should always use the "-w" switch - I do

For testing, always use -w. However, if you reach a point where you're no longer doing anything actively in terms of testing or changing the script, it doesn't hurt to turn it off for production use. The real question is whether it's reasonable to turn off Taint checking for production use, or whether it should always be left on, and I think this depends on your specific circumstances. I leave it on, personally.
