For me the HL is a change, but I am trying to see if it is a good one. I am probably at 9 pts hl now, but on an XL. The advantage is that the head speed on serve is vicious, volleys are easier, and most important, I can whip approach shots into corners a lot easier than with HHeavier sticks. I also think that lends this racquets appeal to folks who like their sticks in the upper 11 ounce range and above. You can weight this racquet up and still have a lot of whippiness. What I notice from old school to modern is when I was young, these sticks were 355 grams and up. Now a lot of people (including me) are playing between 335-345. So to have that weight flexibility makes this racquet much more of an option for a wide range of players.
