Half Walls vs. Full Walls vs. Invisible Walls

There's probably already a thread about this some where but I couldn't find it (probably because I made absolutely no attempt to look for it ).

Anyway my specific question is in terms of regular wall Slam Juggles.... other than the speed at which the opponent recovers from the second slam into a half wall: whats the difference between a Half Wall and a Full Wall ?

I don't think I've ever had to modify my wall slam combos for the different walls so is there something I'm missing ? Am I...
