wooden slazenger > alluminium racket > prince graphite racket
More recent times: Prince Triple Threat TT > Prince 03 Blue (one of the best rackets I've ever had)
Worst or rather most "demanding" buy: Prince EXO3 Tour 100
Great racket > but overly terrible on serve
Hope my switch from the tour to the Wilson BLX Surge 2011, will be a good move.
