I took some pictures of the frame this morning. I think that my wife will provide me with some help as I have never posted pictures before.
You question about ride characteristics is a really good one. I chased this issue down until I got some reasonable answers. Generally speaking I think that the D-Fly will be more stiff due to the fact that there is Boron in the three main tubes.
As far as my bike goes, it is a custom frame. The geometry is different from a Stock frame. The primary use of this bike will be for Supported long distance cycling. I am in the process of making the arrangements for a ride accross north America.
Craig should be able to build you a bike that fits your exaxt needs.I went to his shop and he set me up on his size cycle and we were able to dial in the various aspects of the frame design while I was ridding the sizer. This is diffinetly worth while.
I hope this answers some of your questions......Dave
