i'm noticing alot of decent players who play 1HB do a little shuffle hop to set themselves before hitting 1HB. 1) have others noticed this??? my guess is yes... i.e. is it common?? 2) seems like it's something that could be exploited aggressively. step inside the baseline and hit hard, flat shots to 1HB.... 3) what types of balls in general do 1HB (which i find somewhat rare at intermediate level) not handle well? at french open, they said topspin brought ball OUT of federer's strike zone/comfort zone. thanks in advance.
