I will give the suggested rackets and strings a try. I don't want to do any costumization though. It would be best if I liked the rackets in stock form...
I've been using Alu Rough ever since I switched to the K6.1 (shortly after its release). I know that the "magic" only lasts for a few hours. I'm always keeping an eye on cheaper alternatives though and found some good suggestions on this board here. Unfortunately, nothing seemed to be as good as Lux is in its few hours.
Once I used a BB alu rough / Babolat VS Team hybrid, but it gave me even more power and I had a hard time to keep my shots in... :-p
