This was inspired by Wilmer's Vibrato discussion. How would you describe your hand position on the horn? My left hand varies. sometimes I dig in and shove all my fingers in, pinky on top of the 3rd slide and ring finger in the ring (if I really have to get on the horn for the stronger side of f to fff) or I back out to just the tips if I have to play something really technical or light, and then the pinky goes under the 3rd slide, thumb just barely in the ring on the 1st slide. Right hand is curved like the letter C or gently holding a tennis ball, thumb between 1st and 2nd valve casings under the leadpipe, pinky floating above the ring.
