I'm 5'7" and yeah I noticed the swing speed. I'm going to slowly up the speed on swing. Last time I tried a full out swing I almost took my shin out so I'm hesitant to go all out. It just feels like the racquet is so unwieldy compared to what I'm used to
I'm using a BLX Pro Open vs Yonex Nanospeed 9900 (86g)
I'll keep practicing and upping speed and will post a updated vid in a month or so to see if any progress is made.
