after demoing a bunch of sticks, im beginning to feel some arm soreness/beginnings of TE. even with vibration dampeners, which i know dont do much but still help, im realizing more and more that im sensitive to vibrations and off-center shots. im a good player (3.5-4.0, pretty good strokes) but after demoing a bunch of frames across the gamut of head sizes, stiffness, weight, etc., im still having some issues. i know there are a variety of factors, and that it's not entirely a racket issue, but im trying to weed it out step by step. it kinda sucks because ive found some frames i like but just seem to tear up my arm. which brings me to princes - ive hit with a few princes in the 'o' and 'speedport' series, and these 'o' things seem to be legit. im curious to hear what others have to say about it. it seems like b/c of the way the 'o' rackets are designed, it makes the sweetspot bigger, and subsequently mutes the frame. i know that it isn't everyone's cup of tea, but does this in theory help with arm issues? and with a racket like the speedport black, with such a high stiffness, is it still a legit theory? and are there other technologies i may be missing that help with similar issues?
