TIP: (if it hasn't been said already) squat.,kneel, bend, lower or otherwise adjust your head position in the opposite direction you wish to gain a positional advantage in and hit reset.
For example: If I squat down and hit reset, I'll have gained a height advantage when I stand back up equal to the distance my head was lowered prior to hitting reset. Same thing works for left/right. Another example; turn your head left 90 degrees and hit reset (center) view and then turn your head to the normal forward position, you'll have turned to the right 90 degrees. This works great for looking around without having to twist your head like an owl or stand on a ladder.
Yes this is a classic but it still is only an extension limited to the width of your movement zone. Which is still not enough for me to get all the way to my asp window unfortunately. I really want to invest in the above
