I have a head liquidmetal radical MP that I bought when they 1st came out. I recently bought a 2nd one as a backup during tournament play. However, since they are discontinued, I could only buy the prestrung ones made in china. I can immediately feel the disparity in feel & weight. I've weighed them & the austrian one is 11.2 oz just like the specs say but the chinese one is 11.5 oz --- it seems like little but it's noticeable, especially when switching from one right to the other. The austrian racket has a more solid & controlled feel while the chinese one has a hollow feel & an odd sound to it. Anyone else have the same experience?
