The S&S coupled frame is a zero-compromise platform. Shipping is a little more complex because of the disassembly, but if the most traditional ride feel is what you are after, I think you will be hard-pressed to beat an S&S coupled bike.
Another folder option might be the Dahon Tournado (
http://us.dahon.com/bikes/1672/tournado). I have not experienced this bike myself, but everyone I have talked to with a recent Dahon says that the customer service is awesome and they love their bike.
I owned a Bike Friday New World Tourist with 406mm wheels (now called the Pocket Rocket). I also owned the trailer/suitcase. It is indispensable and immensely rewarding to be able to ride my bike to the airport, pack it up, and then get right back on my bike at the other end. I only incur the extra bag cost (never tell the airline you have a bike).
Your height will be mostly inconsequential with a Friday. They design the bike around you. You will have a little more leverage on the masts because of the height, but I think this will work to your advantage (more on that in a moment).
Make no mistake, even with experience, packing up a BF into its suitcase is a 15 to 30 minute affair. Allow yourself at least an hour you try to pack up a BF.
As Bogiesan mentioned, the BF (like anything) is a aggregate of compromises. Interestingly, the compromises add up to way more than the sum of their parts. There is flex in the stem, but this works to smooth out the bumps transmitted by the small wheels. The small wheels are insanely strong; I built up a custom set of wheels with 28 spokes and those wheels took loads of abuse on Vermont roads. BFs also accelerate like a shot from a gun.
Another surprise was the stability at speed. I descended Vermont and Oregon hills at up to 48MPH without any hint of shimmy. If anything, the BF was quite confidence-inspiring. The only platform I have ever ridden that was more stable is my Burley tandem.
Service and support from Bike Friday is stellar. Their frames are guaranteed for life, and you can always get parts for your generation of BF. They even have a retrofit service to allow use of modern components on older platforms.
Bogiesan also mentions the Bromptons (English folders). They are a cut above with the exception of size of fold. Bromptons do not fit into their own suitcase. Or any suitcase.
