here we go again. i love these threads. all of us talking as if we actually know. perhaps old msg. board staples like pro stringers michael ludwig or thomas martinez can shed some light on this subject. i think (here I go with my fake knowledge) that the generally accepted theory is that he is either using a modified original radical trysis/tour (yes, the one that Head is re-releasing), with different weight and string pattern, but same mold, or just a completely custom stick. i'm sure his original radical (the one that he actually uses/used) was spec-ed out with the POG in mind, as was his old donnay pro one. some theorize that he's still using either of these two rackets, the graphite with the bar cut out. the beam width and head shape of those two are completely different than his standard "radical". everyone knows that through the years he's changed string patterns to suit his game, and around 2004 or so went to a slightly smaller headsize for a little while, and last year and parts of this year, has played with the instinct, both with original and radical paintjobs. he seems to have always gone back to his "radical".
