I like flying both my helis and airplanes with thumb only so I have the rest for the switches and sliders on my JR. I also use a neckstrap for more support and as insurance I dont drop the radio. I tried the other grip a while ago and it felt weird how I had both of my hands positioned above the radio. After a while my arms would get tired. If I am doing a snappy maneouver or jumping in on a torkroll thats about to fall out, I prefer thumb grip because it allows me to respond quicker than the thumb and finger grip. I dont know why, to me it just feels good.
