Halos are a softer ski with a tighter turn radius so you can make much quicker turns and the soft tip and tail make it easier to butter. Aren't too stable for higher speeds and bigger jumps but based on what you said earlier, that shouldn't be an issue. The Halo is the lighter of the two skis. If you're looking for something light but not quite as soft as the Halo, the Alpha 1 is a great choice. The shape is identical, but they are stiffer and have Armada's Competition Base, making them faster but less durable bases for rails in comparison to the S7 base on the Halo. Filthy Rich's are stiffer than the Halo and have a wider turn radius making for longer turns, increased stabilization at higher speeds, and a bit less playful. The Filthy Rich is a better all around ski in that you can ride it on more than just rails whether it be jumps, groomers, or heavier snow. Both skis are rockered so they have the early rise in the tip and tail making switchups easier and making them a bit more forgiving. Hope that helps!
