would recommend sandwedges on any type of lies?
same question for LW?
same question for pw?
or is it all in the execution?

Avoid using the Sand Wedge in those situations where the Bounce of the Club -- usually its greatest asset -- becomes a liability. Namely, where the Bounce off a hard surface, e.g., hardpan or bunkers with wet sand or little sand, could cause the Leading Edge to 'bounce' into the belly of the Ball. In those cases, saftey calls for the Club with less Bounce. And don't be afraid to use that Pitching Wedge to hit well behind the Ball and thus "create your own Sand" in Bunkers that have little.

Generally, poor lies are not a problem. Just move the Ball back in the Stance a bit and make Impact with a decided Forward Lean of the Shaft. The worse the Lie, the greater the Forward Lean.

Remember, too, that Uphill Lies add Loft and Downhill Lies take it off. With the normal Pitch Shot, take Gary Player's advice and "Aim for the top of the flag." That goes double when the lie is Uphill, whether from Fairway or Bunker.
