Henman is a great player, but unfortunately he is not in his prime anymore. Definitely his age and his style of play (all those years of jolting right and left for volleys) have taken a toll on his body. Just look at how injury prone he is nowadays. Plus he's got two kids to look after so he may not be committing as much time to the practice court as he used to before he had kids. Anyways, chair ump, if you do a search of previous posts, Henman's racket specs have been discussed and posted numerous times. If I recall correctly, I think he strings in the lower tensions (approx 42-45 lbs) with TIMO 17G in the mains and VS gut 17G in the crosses. He does mention on his website that he varies his tensions relative to the court surface he is playing on.
