I demoed BLX Blade 98 and tour version two weeks ago.For me, I own one K98 now,and one k93.The new blx version of blade line are softer than the kblade,maybe K98 is 67 while BLX 98 is 65.Another difference is that K98 beam width is 20mm, the blx 98 is 21mm or so(official said 20.6mm). K93 has the same difference.
Both racquets feel slightly more dampened.I like blade 98,it has more pop and more forgiveness.Bothe flat and topspin are Great!Maybe the pink paintjob is more great .Good racquets deserve to buy.
