got the 200hits one for free a couple of weeks ago. been using the 'shotpal display -> OFF' under the Menu -> options but they keep showing up after every cache cleaning.
finally i tried using them up on practice rounds, feels good to finally see my meter clear of that nuisance. so yeah, best method: use them up until theyre all gone. i even maxed out all my shots for each hole in practice mode just to get rid of them quicker.
but be careful when you're down to the last hit tho, the option of 'buy now for 50 creds' auto pops up, the big beartrap you'd definitely wanna say no to.
