Replying to Elizabeths

Ok to start I'm 5'9-10, 150 pounds and I'll be skiing the west coast(Mt.Washington for those of you who know were that is). I ski about 40% park and 50% everywere else. I have found a pair of Line Elizabeths at my local shop that are on sale for a price that I can afford but before I get em I have a couple of questions about the ski. Right now I'm riding the Armada ARV in 175, what is the flex on the Elizabeths compared to the ARV? Are the Elizabeths too short or will I not notice a difference in length from my ARV's? Were should I mount the Elizabeths and with what bindings?
