As expected, I didn't like the racket at all (98 18x20 Gen 3, but I know I won't like Gen 4 either if changes are subtle). Warming up and playing down the middle was fine, as the racket has good control, surprising spin, good plowthrough and maneuverability and feels quick through the air. So when you don't have a lot of variables and play a lot of balls, it is easy to find the subtle sweetspot. Also, I used to play 18x20 Radicals and18x20 Blade, so the low launch angle sort of felt familiar.
But this comment was not an exaggeration, it might be the most muted racket I've tried too, even with a leather grip on (more than Blade v8 in my opinion).
When playing points problems started to come. Once you loose your timing it is very difficult to find it back because the racket gives almost no feedback, it is like you have to find it on "trial and error" but without knowing where you hit the last ball.
Also, a significant drop in power vs. the PD98 when on defense (when playing offensively and using your body I would say the racket is pretty powerful for a 98 18x20 control stick). People tend to criticize Pure Drive feel, but for me they are actually very good for touch shots when you get used to them, as the feel is very raw and direct. For me the only problem arises when you miss the sweetspot too much (either you play really used balls, have bad technique or the opponent is simply better and you are late too often), that is when elbow can feel it a little bit.
I'll definitely stay with the PD and try the new model when they launch it.
