The Lockdown is nearly unstoppable against a guy who knows how to play it. You can avoid it, yes. But if you know how to control your opponent from there it's pretty much a guaranteed sweep. I believe the Electric Chair is the most powerful sweep in jiu jitsu. I've used it effectively against every level of player that I've ever rolled with or competed against. Some guys are great at avoiding that game. Have a solid contingency plan for such animals.
As for the Whip Up, if it isn't working for you it's likely a timing issue on your part. You've been grappling for 9 months; I think it's fair to say you've probably got quite a few more years on the mat before you develop the kind of sensitivity, awareness, and timing needed to begin understanding the beauty of sweeps and the principles that lie underneath them.
Don't give up on it. I promise it'll make your half guard game amazing and powerful if you will commit to learning it. It is, in my opinion, the most high percentage game you can play from the bottom.
