First, I've heard of quality control issues with this one, and while I didn't have a chance to try different one myself, I could see from some photos that the total blade head thickness can be different, even the Plies can be of inconsistent thickness.. but another issue that can affect reviewer ratings is the fact this blade may not at all perform well in the beginning, it really needs to break in!In the beginning, it was like a different blade, slower, throw higher, sweet spot really small! However, after some weeks of use, the sweet spot is actually pretty big for a wooden blade, and the blade is pretty consistent and powerful. It has sort of a hard feel very similar to PG-9, which is rather surprising. However, the dwell time is definitely longer with this one. The throw also noticeably higher, much easier and spinner to loop with a Chinese rubber closer to the table. As it is now, it is a wonderful blade for its price!
