PP, I like what you've been doing on the HB!
Did I miss this last Dec/08, or did you just post it now? I don't remember seeing this vid before.
In fact, I seem to recall a much more inferior whip drill.
I don't think you showed your run/jump/swing drill before.
First of all, great job on the whip drill. I think the mechanics are all there. You're keeping your lead knee up, and you're swinging "just about right". Now all you need to do is increase the tempo ... A LOT!
As for the run/jump/swing drill, I agree with AC for the most part.
You just need to jog into it (as you are), but your jump should be more vigorous - try to simulate a PV jump closer.
I disagree with your diagram where you propose that you catch the bar on your way down. Why? I think it's better to drive up and into the bar ... so violently that the bar will stop your upwards/forwards drive ... to kinda simulate the jolt that you feel when the pole hits the box ... and then you should use the FEEL of this impact as your mental queue to "attack the box" (which doesn't make much sense becuz there's no box there - but just pretend there is) ... and then whip that trail leg like hell!
Remember that BEFORE you catch the bar (just as before your pole hits the box), you need to get into that good forwards-leaning body posture ("finish the takeoff", "get into that elastic stretch", "jump to the split", "stretch to the C", blah, blah, blah) that's going to set you up for a vigorous downswing with your trail leg.
As you catch the bar, you can let your chest drive thru JUST A BIT, but if you pause too long by letting your chest drive COMPLETELY thru, then you're sunk ... then you're becoming too slow and too passive. Remember ... pop in ... pop out. Arch ... hollow.
Whenever you do these drills, always imagine how it should feel on the pole.
BTW, on your run/jump/swing drill, you're dropping your lead knee way too much. You probably know this, but don't have the strength to prevent it. That's normal at your age. You need to do lots of one/two-legged situps ... lead knee drives with your ankle strapped to a bungie ... leg lifts on HB (as you demo'd) ... and anything else you can think of to improve your lead leg strength. You need to make your muscles SUPER-STRONG so that your lead knee won't drop on this drill. If it's dropping on this simple drill ... when you're just jogging into it ... I can't see how you can possibly hold it up properly on the pole.
As far as elaborating on finishing the swing in #3, remember that it's the same as on the pole. Once you pass the chord, the upswing isn't important at all. You make-or-break 90% of your vault on your DOWNswing! After that, just coast to a stop the best you can ... as per the hinge drill. The IMPORTANT part is the downswing. Just focus on perfecting that ... the rest doesn't matter ... much.
