as my second pair of armadas, I love my thalls. this years model has a dope graphic and is absolutely a sick all around ski. I do more jumps than rails, probably around 80 percent jumps and 20 percent rails, i usually avoid rails only because I suck but I do feel more comfortable with the thalls on rails than ever before. for the jumps I love them because it feels stiff, yet easily buttery. seems to have a low swing weight when doing spins, i pulled my first 900 the other day. I can honestly say I am in love.
I have heard nothing but good things for the on3p skis, although I have never ridden any myself I hope I will soon. I know all the kids that use on3p filthy riches at my hill are amazing at rails and usually compete in the rail jams alone.
hope it helps
