I have owned many blades over the last 5 years. Amongst them are: Primorac Carbon (x 5), Gergely 21, Kreanga Carbon, M.Maze (x 3), Petr Korbel (x 3), Schlager Carbon, Oh Sang Eun (x 3), KLHS, TBS, Viscaria (x 2), primorac off-, timo boll spark, Keyshot Light, sk7 alpha (x 2), Stiga Clipper Wood, Nittaku Acoustic, KCZ, Septear, Spintech 9th Wonder KC, and Carbo Gold. Out of all of the blades I have tried, I feel like the PC has the best mix of power, control, and feel.
It is very good at blocking and hitting close to the table because of its hard feel (unlike wood and alc blades) While at the same time it is not to head heavy because of its thick handle and thin 6.9mm head thickness (compared to SC 7.4 and G21 7.0). It also has better feel for the ball too than the SC and G21 in that the SC feels stiffer and softer giving you no feedback and the G21 is so compact and thick that vibration is completely cut off. The KC has much more vibration than the PC but it feels very unstable close to the table and very springy. It feels the fastest out of all the blades I have tried when I play touch shots. Its a blade that has to be tamed rather than something you have to adjust your topspin strokes to like most carbon blades.
Compared to all wood and alc blades, I feel like those have the advantage on soft touch shots close to the table. Looping close to the table is easier with wood and arylate blades but not that much easier with alc blades (compared to the PC). However wood blades take much more effort to hit fast and block with and top out win you hit the ball with a certain amount of force. ALC blades are ok close to the table but do not match up with wood blades when looping at the table or carbon blades when playing mid distance. They are okay at everything but dont really excel at anything.
I play a third and fifth ball attack game. I feel very comfortable playing a mid-distance looping game as well. When I play aggressive players I block, counter, mid distance loop, and mid-distance curve loop a lot. When I play defensive players I play an aggressive push game close to the table an set up my opportunities to put the ball away or I will hit really fast serves to their weak wing and blast a winner with my backhand or forehand.
I you play a consistent loop game close to the table then I recommend the primorac off- for feel and consistency. If you play a topspin loop game close to the table and at mid-distance I recommend the M.Maze. If your game is based on picking your shots to powerloop close to the table (you cannot play a loop everything game at the table like an all-wood blade and sometimes an alc one) or playing a counter game close to the table and a consistent looping game at mid-distance than I recommend the PC. It is a great value, a bestseller, and has great feel depending on what rubbers you use on it. I use Tenergy 05 on the forehand and Bryce Speed on the backhand.
