As for what the coaches always seem to say... many are so old-school, but with Korea's success at Amature and pro levels, there is a method to their madness. if coach says one should use a more forward swing and contact the ball earlier, he or she usually knows what is going on. If you play more of a driving game as opposed to spinning the ball up, you will like any of the Galaxy T-Series. All of them are rediculous fast and very crisp. You would prolly like the T-8 the most as it makes drives and has a small ability in spinning over the rest of the T-Series.
For me, the T-Series blades simply did not suit me. Not that I couldn't handle a fast blade. (I think T05 on a Schlager Carbon is very controlable for the kind of game I play) It is that that when trying to slow and medium spin the ball, the ball left the bat too early to get the spin I need, even if I put on a turtle-like slow soft sponged rubber. I rely on teh spin and feel for control. The t-Series didn't have it for me, but that doesn't mean that there are unusable blades for some players.
I know a TAK9.com sponsored chopper who uses a Nexy Oscar (an Arlyte/Carbon blade that is about as fast as Schlager Carbon). The Oscar is not only top-end fast, but the ball leaves real early. It is suited to those who speed-drive at top of bounce,which a lot of old-school Koreans do well and also just about all of the females do.
