Swiftpoint Z3 vs Razor Viper v3 for fps

I currently have the Z3 ordered and waiting on shipping, however I have never really paid attention to mouse weight. I’ve always used a Logitech 502. I’ve fallen down a rabbit hole unfortunately about light mice being easier to track with. That being said Im thinking about getting the viper v4. Do yall think the weight is just over hyped. My main problem is tracking. viper is 49g and z3 is 138g tell me your experiences please
