I just converted my 1.1 double to a whoopie. It weighed in at 1 lb 8 ounces. My wife's 1.0 double with adjustable webbing, carabiners, etc...weighs 1 lb 12 ounces.

Pretty simple conversion.

I trimmed the stock webbing straps to 6 ft. and got rid of the biners.

Looks like I'll be ordering a whoopie for the whole family.
