At the moment, I'm switching back and forth between the 100X U and the 700pro and I tend to like the 700pro more, as it's faster. However, it feels more demanding. I assume it's because of the wooden handle, as I'm used to the freecore one for years now.

So... does Victor have a similar racket with a freecore handle?

With similar I mean just as flex and just as fast as the 700pro. While the 100X / U isn't slow, I can defend a lot better with the 700pro. I also noticed that a real stiff racket isn't the best for me.

Sounds like you might be looking into the Bravesword 12 classic. Not sure if the newer version has freecore or not but would be in the Nanoflare 700 speed range with flex in the shaft.

Anything newer is stiffer. Even the driveX models are not nearly as fast as a NF 700.
