Are you willing to upgrade to Aero wings to benefit from the much commented lower drag and leeward wingeffect.
The size of the wing is increased, allowing to create more righting moment, and without the compression struts you can use a longer DS sail that may go further down, covering most of the mast stump. The professionally made strong curved front wing bars can be supplied with or without the cleat plates.
Most of the price reduction comes from not having to change also the back wing bars, only the front ones, and only need to adjust your existing tramps, not to replace them.
The shape is similar to the ones used by Rob Greenhalgh in the Perth Moth Worlds.
