good point about what may be around the corner, but by then this newly engineered product would have some real life testing and what's new, maybe too new,  which is Eugene's problem sometimes.  definitely LTD's and we see how that has worked. as well as  the lack of taking time to plan ahead.  no foresight in planning and research has made Eugene's roads the wonder that they are today.  we've done cement to death here...and wood for that matter...hmmmm - maybe glass.....
