I was just wondering, for all you nanospeed owners... I've read in a lot of places that the nanospeed series, especially the 8k and the new 9k, are quite fragile and that is worrying me... I sometimes play with younger people and they tend to have bad experience, and racket clashes are not uncommon. The clashes are not extreme but still make a good clatter. I was just wondering if the nanospeed series (specifically the 9k) are able to withstand some clashes... How is their strength compared to, say, an AT800 4U or a Isometric 90VF (My old 90VF has been quite durable throughout my beginner years, and the AT800 4U is just for comparison).
