if new and good condition. sure. but if old and banged up. probably not. and make sure you find a good stringer to do it.
No. It's about the structural integrity of the racquet and being able to distribute stresses/loads well during stringing. Any racquet that is damaged has a potential to break under load. The damage that is sustained may not always be visible as there could be fine cracks say around grommets hidden by the paint. So even a small clash could inflict damage that may seem ok but under the surface there may already be tiny cracks forming that may be exacerbated when under load.
No, the exact same thing applies for Apacs racquets too, as well as all other badminton racquets, save for the really cheap brands that feel light and have an uncanny hollow sound to the frame (very obviously if a racquet is of such cheap quality please do not expect it to withstand even "normal" tension). Try stringing up a damaged Apacs racquet to your 28-30lbs tension and see if it holds up, then you will know. In fact, Yonex racquets are a lot stronger (in an underrated way) compared to Apacs racquets. Simple reason being that Yonex racquet frames are relatively thin and yet they are able to withstand very high tensions especially that of professional players (who use up to 38lbs), while the relatively thick Apacs racquet frames can only do so similarly by bulking up the racquet frames (which translates to more mass, bulkier cross sectional area and less aerodynamic).
yonex is maybe trying to make the racket last longer because if you tie higher tension strings, the more fragile your racket will be! and if everybody ties 30~40lbs, the chances of breaking the racket increase, and if you're the boss, can you pay so much? well, just thoughts
i had strung my apacs racket to 30lbs (hi end apacs racket) but i wonder if yonex racket can adapt such tension..because there has limit to 27lbs..huhu
The Yonex limit is for warranty purposes, yes pros string theirs much higher than the stated warranty limits but that's pros. So if you string yours above the limit and it breaks guess who pays for the racket?
