Back to doing a few surveys; I manage to get enough from them to keep me in balls. Using the Play9 ones atm,
If you really want a decent ball to go with those irons, check out the Tour-SD. I used that combo to get to Legend way back when and at 65 credits a sleeve, you'd get 3 of them for what you're paying for those Play9s. Little less distance and a faster meter (which I liked) but very easy to get used to and they play well off ding. Great value.
FWIW, I went from those to the 33 Callaways which were the cheapest decent balls. From there I wound up with the cheapest Nike which I use to this day with great results. You're wise to lay off the expensive ones at this time.
