Model O , Aerox 3 , G703 , G305 , Roccat Kain , Pwnage ergo and symmetrical , Deathadder Pro. Honestly , i'd take 305 and 703 over GPW any day solely for the shape , in fact i use both over GPW. FK1 shape seems to be a bit overused and over-cloned? but good regardless (Model O / Viper) for fingertip (or claw grip if you have smaller hands). You even have cheap-ish options like deluxe M800 and Fantech XD3 (Zowie S2 clone) nowadays if you don't want to break the bank. Hati S is another interesting shape to keep in mind , unfortunately they Gwolves really struggle to keep it in stock. Cooler Master is going to release a new ergo mouse soon and MM711 wireless in future. So plenty of better options (shape wise , *imo*) over GPW and Viper. Also , G703 seems to be running out of stock everywhere lately , so i wouldn't be surprised if Logitech release "lightweight" version of it in couple of months. Roccat is going to release a wireless mouse some time soon too but not confirmed if it's going to be the old Kone or Kone Pure , Q3 or Q4 of 2021 Endgame Gear is going to release wireless XM1 (superb shape).
