Drashner, I think we're in vehement agreement. Travel one way and gain ten years, travel the other way and lose ten years. Different places in space-time are linked via wormhole with one metric and via flat space with another metric, and both linkages work subject to the same physics, in both directions. But there's no metric, and no combination of metrics (closed timelike curves) that would allow you to reach your own light cone at a speed less than c.
Rynn's example where two travelers take trips lasting 16.66 years according to the first-light framework, but have subjectively experienced 3.2 and 12.8 years respectively, sounds correct to me. He's right, on further reflection, about the direction of the clock adjustment involved in traveling from the older to the younger end of the same wormhole.
