Tom2;

When it comes to matched pairs (steel/nylon) you an others will have to pull the wagon. Nylon has been my objective because that is what I like and that is where I think the biggest challenge is in a contemporary hybrid competing with a good traditional classic guitar.

Given your analysis of the ideal X10 I could see myself ordering yet a 3rd version (sometime in the future). In the meantime, my X10-OSN and RS Parlor serve me well. Speaking of the X10, would your ideal have a center or off-set sound hole?

Also in the meantime, I am hot on the trail of a X7-based nylon electric. I believe that contemporary electric nylon string guitars can be bested and look forward to an early prototype of the future.
