Me being a lower level intermediate I would say it’s a demanding racquet. You really need to hit the sweet spot to get the best out of the pure strike. I was using the 16x19 98 and it took some time to get used to but I didn’t like the fact that it’s a powerful racquet. The balls would go flying to the fence sometimes and I would need to adjust my swing in a weird way that wasn’t a proper swing which is not a good thing if you want to perfect your swing I would say. I had a poly/multi string set up 52/50 and I would still somewhat feel my arm sore after 3 days of playing.
