I have a tad of OCD. I always have 12 in my bag plus two in my glove to start the round (one in play and provisional). Far rather have a spare in my pocket as some holes it makes more sense to leave the bag bag up the fairway than taking it all the way to the tee, and so saves time should it go wrong.
12? Plus 2? Wow. How many do you expect to lose? My last 5 or 6 rounds I have had 4 balls in the bag. If I lose those, I am walking in. I don't remember the last time I needed 4 balls in a round.
