I second that..... For me it may be because I grew up in the video game age, no need for index finger on Nintendo, SNES, or Playstation (had to be good with the thumb to beat all of my buddies). So I never needed it in RC either.
Good point, never thought of it that way. That explains why when I tried to use thumb and finger it felt terrible. I had 1,000,000 hours using just thumbs on my nintendo as a kid!
