I have been playing with the K-Factor 90 for around 3 years and thinking of getting 1 or 2 more sticks. The question I would like answered from those who have had experience with these 3 rackets: Which of the 2 BLX 90's are closest to the feel of the original K-Factor 6.1 Tour 90? I have heard that the BLX-90 (Black & gold paint job) has much less 'feel' than the K-Factor 90 (more muted / disconnected feel - which I definitely don't want), I have also heard that the Pro-Staff 90 BLX has more feel than the BLX 90 and is slightly more maneuverable and a bit easier to serve with than the K-Factor 90. Would this be an accurate description of these two BLX's in comparison to the original K-Factor Tour 90? Can anyone add their opinions and / or recommendations based on their playing experience with these rackets?
