Replying to Armada ARV 86 or 96

So I am going to either get The ARV 96 or 86 for my next ski. I currently am using the line TW shorty and it is super light, but the 149 is too small for me. I am 5 2 and 100 lbs, and can do 7's, 2's out of rails, learning to swap and need a durable ski. Should I take the jump from a 75 mm waist to a 96, or just. go for the 86 and have a lighter weight? I am planning on getting 163 cm. Any other skis you have in mind?
