Rob, something else to think about along those lines, at one point I crunched some numbers. From the published info, both Blind Date and Rare Bird clocked in at a very similar rate for hours / pound. Rare Bird was .67 hours / pound and Blind Date was .71 hrs/pound.
Until someone finishes an infused design or at least gives an official estimate, you could scale those figures by the estimated 25-50% savings, and apply to the weight of any design. I like my dreams to have numbers, even if I make them up or infer them...
Is there a weight estimate for the Cruiser 60 yet? I don't find it with a quick review of the group.
