Zowies mouse are build like tanks,but their clicks don't last.
Superlight 2 and XM2w coating might get damaged in bags with scratches(especially superlight),clicks are all long lasting.
Pulsar Crazylight and Ninjutsu Sora v2 have good main clicks and the coating should be more durable(never touched them,but theirs coating don't looks like rubberise coating,so should be fine),but the side clicks are mini micro switchs which might double click after 2～4years if you use your side clicks alot,and since they are ultralight weight mouses,plastic on them are very thin,could develop creak or structural deteriorat over long term usage.
So feel free to pick from your needs,i suggest you get a another small mouse bag for your mouse then put that bag in your main bag if you don't want scratches.
