I think jimmy arias is pretty cool. becker is funny so I don't mind listening to him once in a while.
I also like robby Koenig.
cliff drysdale is ok too.
johnny mac talks too much and Darren Cahill acts like he knows it all.
I don't really dislike him but I rather listen to the others if I am going to listen to anybody at all.
and truth be told, quite often I just turn off the volume so I can enjoy the match quietly. also it allows me to do some of my work too with out too many distractions.
