very tight tension and average tension? for me opinion onlyyyyyy please dont get mad for my non professional my opinion; the tighter the tension, the more power u able to create. good for pushing and driving shots (bird goes faster) overall for all the shots that require fast pace (if that's how you spell the word =) ) the tighter the tension the better. however, high tension takes whole lot power out of you. (that's wat i heard only =) i don't have any problem with clearing, smashing either i can't feel it. Unless there is 2 exact racquets with different tensions being there for me to test it.
