Spycheck with your body, if you bump into someone, say that they are spy, at worst one idiot that isn't paying attention will get stabbed. At best it's another ubersaw hit.

This works fine in theory, and even has decent returns in practice. Fact of it is though, if you take the time to try to go through everyone before you heal them, a lot more people are going to die.

During a firefight, it's pretty common for the medibeam to hit 4 people or so over a 5 second span. Trying to run through everyone before you heal them cuts that down to (probably) 2/5.

For my money, it's better to overheal a spy once every (warning, random numbers ahead!) 3 minutes than to have 20-30 premature deaths in that same time span because I'm going to melee range before healing.

/shrug, ymmv

I meant heal everybody and run into people as you heal them. Most spies are very obvious anyways so it's pretty apparent whether or not you should heal them.
