Thanks Jeff, some good insight. I actually know the Quantum sailmaker here in Seattle (part of my club) so I reached out to his this AM to get thoughts and a quote. Will keep you updated via this discussion as I learn/decide more...
Here is the response from another sail maker who is steering me towards Dimesion Polyant Pro Radial (http://www.dimension-polyant.com/en/pdf/DP_Pro_Radial_E.pdf) which sounds interesting. Anyone have experience with it? Here is what he wrote:
Instead of going with a double taffeta cruising laminate, I chose a fully woven radial cut dacron.
The pro radial from Dimension polyant is extremely low stretch, durable, and will not mildew as the cruising laminates like CDX do over time. We live in a moist climate, and I feel the radial dacron sails are now as good performance wise as the cruising laminates with less issues down the line.
These will be great cruising sails, that will shape up as racing sails. I have been very impressed with the shape holding characteristics of the pro radial.
