I got "The Silent Gladiators" and am at present a little over half way through it.
Thus far I think its been good, but not great. Hopping is obviously passionate about the sport, and the insider level of stuff that he provides has been really fun to read. I really enjoyed reading the stuff about the Sanderson/Fullhart rivalry, and especially the chapter on Saitiev.
Where it could have benefited though was from a very, very vigorous copy edit. I can understand some grammar mistakes slipping through but the fact that the Olympic weights were continually written incorrectly was kind of jarring.
