Anyone can probably use it in a calm situation. But it requires skill to use it like Izumi and Nasu. Let's imagine: you plan to shoot a bunch of for example 25 (5X5) bullets. If you want to use it like a master, you will probably need to imagine 25 different trajectories in very few seconds if you're in battle. I think that's why Hound seems more popular: it's easier to use. But I think Viper is a greater threat with a skilled user.

This is all my speculation. Also, we don't know if Izumi or Nasu have some kind of side effect that might help them in this.
