Italian Andreas Seppi has survived two five-set battles in the Australian Open 2017 and now has a huge test on his hands when he plays Stan Wawrinka in the fourth round (see my predictions here).
Seppi doesn't use any of the big name racquet brands such as Wilson, Babolat, Yonex or Head, but a smaller Taiwanese company called ProKennex. ProKennex has focused on tennis elbow friendly technology they call “kinetic”. Andreas Seppi endorses the ProKennex Q Tour (325 grams version) which is a players racquet similar to the Head Prestige line which Seppi used previously.
I've used the ProKennex Redondo 98 myself and must say that's an absolutely spectacular racquet if you can handle the weight. Arm-friendly, control-oriented, but not powerless and with great feel – it's definitely one of my favorite racquets of all time. I haven't tried the Q Tour series, but have heard from many players out there that ProKennex create high quality racquets.
Seppi strings his racquet with Luxilon Alu Power and wears Fila tennis gear.
