I'm right between Eastern and SW. I've been a 16x18 or 16x19 player my whole career, until this frame. It has taken some effort on my part to adjust to the lower launch angle. But also, previous to switching to the 93p, I had gotten into some bad technical habits with my forehand. Changing to a 18x20 frame forced me to address those technical flaws. It hasn't been all roses and puppy dogs, but it's really coming along now. Now I'm able to accelerate the racquet way more that I ever could with the PA - with confidence that the ball will stay in. Icing on the cake? My slice backhand was always a weapon with frames I used in the past. Now it's even better. Dare I say filthy, totally different level. Even more icing on the cake? In my 38 years, 20 or more of which I've played this game, I've never volleyed this well - both in terms of the quality of the volleys I can hit, and the improvement in consistency. I haven't changed anything technical with my volleys, so most (if not all) of the improvement has to be attributed to the racquet in some way.
Hyper G 18 at 40 lbs was perfect for me. Very controlled, but plenty of pop when I needed it. It continued to get better as it broke in, until maybe 2 weeks down the line it finally tapped out. I've been testing some Tier One strings for the last few string jobs. So far, haven't found anything that wowed me like Hyper G did. I also have a set of RS Lyon 17L to try at some point. But if nothing else, I know I can go back to Hyper G 18 and be happy.
