I use whatever is on sale, but a couple of my favorites are the wilson staff duo elite 50, gamer or gamer v2, noodle long and soft, and i'm going to try out the hex bites that golfsmith has for sale now.
i also do the lost golf balls thing, but the big issue i've had is they are darker than new balls and a lot harder to spot. i've never had a problem with them being waterlogged or questionable internal condition like some people say, but the dark cover definitely isn't ideal if you're looking anywhere but the fairway especially in the fall.
and don't be put off by the whole compression thing. i had no idea what it meant and i swing my driver in the mid to upper 90s and have no problem. the guy i play with swings faster (i'd guess in the mid 100s to 110) and i throw him those duos some time and it doesn't affect his ball flight.
the first guy was right though. get a ball that feels great off the putter. i've dropped a lot of cheap "distance" balls because they feel like rocks off the putter and when you score high you usually could use better greenside shots and less putts and a ball can make a difference on those.
