These lvl 58 G20 certainly are good clubs, and the ATV, too.
More "feel" dots of balls mean that the meter is slower than other balls, and it's costly.
Now you have payed for a slower meter of your clubs already, and I appreciate your current choice of Tour-SD balls. They have good performance at budget cost - IMHO 6 cr per 9 hole stroke game. I've played them long enough and still use them part-time. In prime playing times I estimated my expenses for balls to 10 $ per month.
To save some credits you might consider any cheaper ball. Though their performance is somehow reduced, even the 10 crs sleeve brings a good advantage vs. the Starters!
