Your swing speed does not matter when selecting a golf ball. You have a driver swing speed of 95-98 mph, but what is your swing speed with your 5 iron? Or 8 iron? Or sand wedge? You have a different swing speed with every club in your bag, so you need your golf ball to perform at every swing speed. Yani Tseng has about the same swing speed as you, and she plays a Pro V1x (and seems to do pretty well with it).
When selecting a golf ball, look at how it performs around the green. Your driver is only used about 14 times around, but you have many more shots into and around the green that have more of an effect on your score. A golf ball that you can control around the green will lead to lower scores.
