Wow, there's a group of purist! That's awesome to hear, but I am all for lift clean and place for the main reason when the courses are not its good playing condition . . .
If the ball gets clumps of thick mud, you must not have gotten the roll you should have had, had the fairways been in a decent condition.
Ball with thick clump of mud influences more curve flight on the ball when played with it, I believe-- let alone not sure which way it'll squirt on you or how much. A little dirt, I don't mind-- it won't hurt.
But with the clumps of mud, I'm very ok to say "Let's play Lift Cleand and Place."
