Hi, So, I previously owned a "O" from Luxilon but I bought it on another forum from a stringer. It was therefore what the players were given, since Lux didn't make it avalaible for us (yet). I didn't play with it for now. BUT My old one (lost) was much more soft and flexible. It could bend, and as rougher than the new one. The new one keeps its O shape, is much smoother. Any thoughts from people who have used both? The old one used to kill basically any vibration it was amazing.
