What do you use as a Provisional ball..?

[HomerJSimpson]

Usually a similar make to the ball in play but with a different number or marking on. Usually pretty easy to find as the provisional tends to go where the first one should have. What is it they say is the first unwritten rule of golf - always hit the provisional first

I use the same make for both (Titleist NXT) but have a load with my Company's logo on for the provisional to remove any doubt which is which.
