Have bought MP Tour-5 recently, it's different in feel from my other frames and it plays good (if you wanna know how MP5 plays, read mono posts, they are great) Anyway, when I have broken the original TW string and attempted stringing the thing, I was quite puzzled with numerous engineering flaws in it. Here are a some of them from the top of my head: 1. Weight dicrepancy - arrived 0.7 ounces heavier than TW listed weight 2. Triangular cross section of the head prevents mount wedges of stringing machine to support head, it's then just supported by mount screw at ONE point only, which is not only unhealthy for the frame on its own but also the screw thread scratches the racket body badly when stringing. Rubbish! 3. The distance between 18th and 19th cross at the throat is huge - well over an inch, anyway it's impossible to clamp them together using flying clamp - rubbish engineering! So I didn't tension the last cross at all - just pulled it through and tied it up - rubbish! 4. If it's not enough for you, the distance between the hole where you are supposed to tie the last cross and the hole where the last main goes, is less that quarter of an inch! - try to make a knot - another rubbish engineering! So much to all this talk about Yonexes well made - it was worst made racket I come across so far, in regard to stringing, I must admit. It does play well.
