Reducing my short list, looking for - arm / shoulder friendly, - racquet for attacking players, all around + serve - volley (good kick / flat), - good combo between maneuverability to whip the ball and stability for net game, - like players racquet but want sthg just a bit less demanding, just a bit extra pop (that's why I think also 18*20 not appropriate for n 6.1). Have you guys tested and compared those frames? Reco? Also any stringing reco? Tks.
