2 sleeves of new and a 2 or 3 used ones.
If I ever needed more than that I’d just quit the round and go home.
The most you've used is 3.....is that per hole! I call BS.... do you only play on courses with no water, no trees, extra wide fairways, no cliffs, no hills... come on man you're a 14 cap and par golfers can lose more than that on a tough track on any windy day lol!
I think the most I've used is 3, but I always carry a dozen?
