I noticed that Apeks, have moved from a Horse shoe design to a donut on their Twin Cylinder Wings.  I am in the market for my first one, and curious about the benefit or change.  I found a shop selling the older Horse shot dual bladder for $200.  Should I just get it, or the new donut that much better.
Thanks.
