I palm grip for surfing, work, etc, but go fingertip when gaming.
Palm grip myself. Even with the smaller Logitech M705 I use for work I palm grip but I do tend to claw to the sides of it to keep it in place...
Just checked on my desktop's mouse, it appears to be in between palm and claw grip. My hand lies flat on the mouse but it's not long enough to rest in my palm. I have a Steelseries Sensei [RAW] Frost Blue
My grip is not listed. I guess I should call it palm - pretty much grip with pinkie on one side and thumb on the other side of the mouse in palm position
Im also a hybrid, using palm and fingertips with a bit of claw - mainly because my right hand is all weird looking due to my accident as a kid. So I have no choice, its how I have adapted to use a mouse
