Replying to Armada Halo and Liberty Antigen

Ok, my Armada El Reys arnt cutting it for me this season and im going to have to do a mid season swap, ive narrowed it down to these 2 but if any of you have other options let me know, im looking for a very light and very buttery ski that is amazing on rails and small jumps, i realize you will most likely not find a super buttery ski that is amazing on big jumps. so which of these is the most buttery, will be the best on rails, and some jumps pretty much. i dont need an all mountain ski, just a park specific. other suggestions would be great, with about a $550 price cap. Thanks
