Touring - lightweight travel bicycle

I'm looking for a lightweight travel bicycle. just wanted to check i haven't missed anything.

I will be using the bike for exploring leightweight touring countryside/wilderness and will be flying around countries and thus dont want to pay oversize and overweight baggage charges. frame and wheels has to fit in 26" wide suitcase, mtb wheels

options considerd:

airnimal rhino 1000 10kg
DAhon flo £1500 11kg
sling shot (frame) 1400 10kg frame sus
montague (frame)1000 10kg
ibis tranny 2000 9kg lightest
lapierre passport 1600 12kg
hortst link mtb 1200 10kg
carbon frame 900 9kg cheapest
carbon rear sus frame 1600 10kg frame sus
note: my builds would be super simple (no rear break and no front derailer carbon fork etc)

The options that im most seriously considering is below; because their weight, price and ability to pack, does anyone have experience with them?

thx

I have a Montague Paratrooper, and it won't fit into a bag like how you want it to, but I've taken it on flights as normal baggage.

Bike Friday, http://www.bikefriday.com/ ... you really don't Need 26" wheels .

if you insist, Dahon paid to use Ritchey break-away system in a 26" wheel
separable diamond frame.
functions like an S&S coupler .. down tube has a joint,
seatpost held by the frame in 2 places.
they have a whole Mountain bike with that setup.

yes i dont need 26", however i do prefer them after i think the closest i would get to 20"s of road in a way i would be happy in the airnimal rhino.

do you know where i can find the breakaway frame for a MTB?
