I'm using the gp4 and they're very comfortable for my big hands. I just got them dialed in. I went back and forth in deciding which model to get. When putting my hands on the horns it most comfortable to have three fingers there with my thumb resting on the top. They claim you should be able to do this with the gp3 but I don’t think I could. Yes they are pricey but they made all the difference.
