Penn ATP Extra Duty Tennis Balls
The Penn ATP has a very consistent feel and I've found it to maintain a little longer than the Wilson US Open tennis ball, which is the main reason it ranks first on the list. The ATP ball is used in ATP matches throughout the world and in three of the four biggest US tennis events each year. The ATP ball has SMART OPTIK felt that Penn says is 19 percent brighter than a standard tennis ball. The ATP Ball, like its cousin, the ProPenn, feels heavier and firmer than some other choices. If you're experiencing any elbow problems, going with something softer may be the better part of valor for the time being.
