Even if they are safe, I will probably opt-out but I definitely don't like being separated from my baggage on the belt during the pat-down process.
This usually isn't an issue, you can see your bags or have them set aside. The issue I have personally been running intro (I travel about 2x per month on average, meaning potentially 4 trips through these things) is that when you opt-out it seems like it is taking longer and longer for them to find a suitable pat-down attendant.
This could just be my own skepticism, but it certainly seems that the wait is getting longer and longer each time.
