Alright, I have played with the 16x18 in some sets and changed string/tensions a couple times, and have a new review.
Im not sure why my initial impressions of this racquet a year ago were of this racquet being under-powered. Right now this racquet is feeling quite lively. As mentioned before, it is very comfortable and good at producing spin. I had it strung at 55 with Solinco Tour Bite 16L today for some sets against a good player. I also have 4 grams of lead in the head; 2 at 3 and 2 at 9. This is a great overall racquet and I will probably switch to it.
Backhands are very solid, and with its lively feel you can hit on the run strongly. Forehands create spin, so I found it to be accurate, able to move it around including angles, while also being able to hit a very big ball when attacking flatter. Initially my tension with alu power at 52 and it was too powerful, but with Tour Bite at 55 it helped gain control. I may go up to 56 or 57 for an ideal setup. Returns were some of the best Ive hit, being very solid and powerful, including on the stretch and slice very strong. Related to all of this results in very solid and powerful volleys, great plow through. Defensive shots and slices are strong. I was worried about serving from my brief playtest a year ago, but Ive found this racquet to have plenty of action and pop.
This racquet certainly has a unique feel overall that takes a little getting used to, but its very good in all areas. I miss some shots due to not being adjusted to the racquet and dialed in, but Im hitting some great shots. Some of my best shots ever, things I couldnt do quite as well before, have come on volleys and returns. Most importantly, Im still hitting a very big and consistent ball with more spin than before, and the serve isnt underpowered as I worried. Count me into the club!
