May be some batch issue. I have been using Vega X for 5 months and I think I can still use it for 2 months more. I play around 6-8 hours a week. I used O7P earlier, and I found that it also had some issues when I switched to the second sheet. My second sheet started showing erosion in 3 months.I find the X have durability issue. The Pro has better durability.
Vega China is a H3 alternative, perfect for FH.
I agree Vega Eu goes well with fast blade. Its touch and control is amazing.
