I think most topping trouble comes from being to eager - trying to knock the skin off the ball then looking up to see where it's gone. Every week in practice I spend a half hour or so making absolutely sure my head doesn't move, usually right through to the finish. Of course you're head will always move but I try to keep it still. Actually, it's not the head that moves up and down (though it does turn sideways a little) it usually starts at the knees but keeping the head still definately helps me.

The idea in golf is to build a repeatable action so keeping the address in uniform shape should help you build a good foundation to the swing. It could also be that your legs are too bent at address, rather than just broken, so they feel springy, as they should be. If you can't ground the club at address don't compensate by bending the knees more. You should always bend from the hips which will put you more over the ball when using a pitching wedge etc.

When practicing the address stance, and this is, I think, you're mainly problem here, I find this little saying helps.

* Stand at attention (feet together, chest out and chin up)

* Stand at ease (don't slump just widen your feet .. keep the chest out and chin up)

* Bend from the hips ( Don't let the chin drop when doing this and remember the chest ... I also like to feel the muscles on my calves pull a bit)

* And flex the knees ( now relieve the pressure off your calves)
