with reguards to Braker's big bike, is the main draw back with having such a large frame that it will flex more than a smaller frame? I'm sure i've seen somehwere a big bike with an extra tube (like on the back of a tandem, or on one of these kona's (not the best example).

if it's made of decent matieral would the added weight be worth it for added stiffness?

Short answer: all else being equal, larger frames will flex more (IIRC flexibility is an inverse square function of length - can't find the equation right now though but i'll look it up if anyone cares)

Longer answer: that question can't be answered with the information provided... flexibility is also directly proportional to EI (product of elastic modulus and moment of inertia) so it depends on the material and the tubing shape/ profile.
