How much perfect control speed do you need? The Kinzu v2 has prediction but the prediction isn't as strong as it is in the salmosa. The main problem with the Kinzu V2 is the low perfect control speed.
Another mouse that you might be interested in is the TT esports Azureus mini. Should have similar prediction to the salmosa. This review below says it weights 96g but has 20g of removable weight ( you need to pull the mouse apart and ruin the feet to remove it though). The Azurues will have a higher tracking speed compared to the Kinzu V2 as long as you stick with 400 or 800 dpi. Another thing to note is that the Azurues will probably have a much higher lift off distance than the Kinzu V2.
