^ try both the G304 and Orochi V2 if you can, they aren't meant for big hands though. I prefer Orochi V2 because of the shape and the texture of the buttons but takes a lot of getting used to if you mostly use large ones.
I think G304 sensor is slightly effecient compared to Orochi V2 but I can overlook that advantage as I just purchased some AAA Tipsun rechargeable Lithium Batteries. You can use the Eneloop Pro but it will drain fast as Orochi V2 requires 1.5v batteries.
