I have experiance w/ the kblade 98 and tour and the RQiS 1. I liked the yonex more no comp against the blade 98 while packing some controllable power its lack of spin and feather light weight just turnned me off. Compared to the blade tour I still liked the RQiS more, it had a little more pop and way more spin good for a baseline attacker and, enen w/ its heavier weight, was just as maneuverable at net as the blade tour. When hitting w/ the blade tour I noticed a couple things 1:great feel more then the RQiS 2: spin half as much as I got from the RQiS and 3:little power not much diff from the RQiS but shows on serves. The blade tour in my opinion really shines as a serve and volley stik w/ great touch and feel if you can provide on serve, while the RQiS is a much better for a baseline attacker who loves to hit hard penetrting shots with spin forcing an error or opening up a mid-court or net putaway shot.
Out of all these stix I liked the RQiS 1 Tour the best... hope this helped good luck!!!
