How do you ride your 700s in the twisties?

2nd year guy here, been working on improving my cornering ability.
I'm running on the Folsom, CA Salmon Falls run, it's posted on uTube in a few different vids.
  just one example.

I'm using this as a place to learn and I am seeing improvements, I changed my riding position last time to lean forward with the arms at 90deg, this seems to be much better.

two questions:
1. what is the best riding position for this kind of riding, I'm leaning forward with head fully above wind screen, arms have a 90 deg bend.  This seems to allow better upper body movement.

2. after watching a uTube vid on positioning for cornering, I was a bit confused.  The guy was against moving the butt off the seat, instead he was putting the upper torso forward and off to the side.  This and pressing down on the turn side foot peg was all he was doing.
The confusing part was that others that I've seen have the rider with the butt slid half off the seat.

Is this just an issue if the speed that your taking the corner at?  Is upper body lean enough for slower wider turn and butt sliding more for quick / sharp turns?  or is this more of a preference thing?

While in twisties, I love to ride like the motoGP guys. Stick your knee out (in direction of turn) to lower you center of gravity. It really let's you get low!

Proper body posture while riding is the equivalent of getting a new more maneuverable motorcycle.

I sit straight and bend forward at the hips, not the lower back with my rear end back in the seat where it should be. I stay on the seat and generally don't put a knee out. I slightly lean off to one side with my upper body - when I'm in the twisties, I'll often look over the upper corner of the plexifairing 3 windscreen instead of over the top center. When I started doing that, the bike changed character and became a LOT more controllable. It was borderline magic...without trying I started leaving the 100+hp crotch rockets with super sticky tires far behind.

1. Forearms level to the ground for most efficiency, comfort.
2. The old bias ply tires aren't really taking me to hanging off levels.  I use the Lee Parks method of light leaning, pushing hard on inside handgrip while bracing outside grip with stiff arm before turn, then let outside arm go slack to turn.   On my last bike, I played with getting a cheek off the seat, but it was tricky to do smoothly and was a distraction for street riding.  Supposedly the proper method is more of pivoting around an imaginary point below the seat as opposed to back and forth sliding...but it's mainly theatrics if you are steering correctly and not dragging knees.
