Well, I hurt my hip in some way during this season, and I have totally lost my drive knee, which wasn't half bad. So, I have developed a double leg swing up and I would really like to know if that could be a good thing...or at least not that bad of a thing...so, any help, stories, suggestions, anything would be much appreciated.

yea i was actually about to ask the same thing.. how important is the knee drive in vaulting.. i remember hearing stuff about people who jump with a double leg swing and are good with it. and like watching videos of lobinger he has a knee drive at plant, than it drops down, but then hell bring it back up agian. so ya im also curious to know about this.
sorry ali ive gots nothign. i have heard about people who do have double leg swings and are good, i heard it looks really weird or soemthign though. i remember kids at pv camp last yr talking about this one dude but i dont remember his name

Yeah, I know...I can't understand what to do to fix it or if i should fix it... Thanks for replying!

Yarr...my coach calls this the SD double jump...fong, you're right, he says it does look pretty strange....

But sorry, he discourages using it. I'm not sure why, but I was always told it was a bad thing.

The issue of the 'double leg swing' is dealt with on page 153 of the book "Beginner to Bubka"..

Well the knee drive and the act of driving up puts the most power into the ground which converts into having a more powerful take off. After the point when this has happened some people tend to drop it in order to try and keep the hips behind the pole and to penetrate, then bring it back up in the inversion phase. But from what I've learned, not having a good knee drive creates a lot of energy loss which wouldn't be gained (probably more lost) by an ineffective double leg swing.

Yeah, but i have a good drive knee @ take off, and then I bring my other leg up and swing, i know that it's bad, but I want to know just how bad!

It is real real bad - kills pole speed and you lose the energy input you could get from a whipping swing of the left leg. - you must change it.

If you are focusing on driving you knee you are focusing on the wrong thing. Try this! Take on step with your right foot (right handed) and jump as high as you can off your left! what does your right knee do when you do this?? focus on driving your hands up and forward with your foot! Jump straight up at take off!
