Tips for Using a Hyperangulated Video Laryngoscope
An easy maneuver, which can be done gradually by the operator with no assistance, is turning the GlideRite stylet and tube 90 degrees to the right after insertion through the cords (see Figures 4 and 5). The operator should use an overhand grip at the top of the stylet and tube. After insertion through the cords, the tube and stylet are turned rightward, to the corner of the patient’s mouth, while making sure the tip is through the larynx. The thumb is then used to slide the tube off the stylet in a series of gradual advancements. By turning the stylet and tube, the tube now points downward, overcoming the inclination problem. Turning 90 degrees also rotates the bevel of the tube upward, which prevents the tube tip from catching on the corrugation of the tracheal rings.

Heston LaMar, MDThe proper use of the proximal end of the GlideRite stylet in terms of the “thumb pop” & also using it to steer the distal end of the tube is something that I think very few are taught or know (unless they have gone to a good recent airway course). Depth & angle are also key as you point out (which is why I hardly ever use a 4 blade on our GlideScope).

ML ClevelandCan you include a link to a video representation of using the overhand technique with the 90° rotation?
