The question that you should be asking yourself is what type of "feel" do you want you skis to have. I know the feel of a ski is really not a great way to measure the difference between ski A and ski B since you can't really define "feel" with numbers... BUT it is one of the most important things you will consider in your decision. So, focus your attention away from the binding system, and focus on how each ski will not only ski... but feel on the snow. I have a lot of experience on Elans, but less experience on Volkls (still some experience), so take my advice for what it is worth.
The Elans are going to have a more damp feel. They will feel solid throughout the ski, and offer a good amount of very smooth rebound. I always felt that when skiing Elan skis I could feel the tip and the tail of the ski engaging, while on other brands you only feel what is directly under foot and the tip and tail feel slightly removed from where you connect to the ski. Elans tend to like a centered stance and require less power when skiing them... although they will reward power when you give it to them.
The Volkl on the other hand is going to be stiff and powerful. Flexing them in the shop you can tell that they are stiff. I have never enjoyed them partly because of my size (155lbs). But, for a heavier person they are great skis. Volkls tend to like to be driven... not ridden, if that makes any sense. Essentially you won't be able to be lazy on them. They may out perform the Elan on groomed snow (if you can bend them) but give up performance, or at least user friendliness in rough terrain such as crud or bumps. They will like to be skied forward (Volkls tend to have stiff, short tails). They will also reward putting power into them with a strong snappy rebound, but if you can't bend them you will feel like you are bouncing up and down on a 4x4 peice of lumber.
Hope that helps. I would steer toward the Elan just because you are aspiring to become an expert skier. Jumping onto too stiff of a ski too soon can hinder your development. It isn't a question of which ski is a better performer, because even I, at my low weight, could take the ski out and ski on it and you may not be able to tell the difference in my skiing... so both skis are fully capable of skiing the same terrain with the same rider piloting them, but one may suit your skiing style and needs more than the other.
