One thing to look at when you get a tall frame is not just the size, but the wheelbase. I am a lazy ass slacker and always liked a longer wheelbase for the comfort of the ride. I don't like twitchy handling. You should be able to smoke a spleef, chug a Czechvar and still have the ability to cruise and not crash!
I am working on a Raleigh R300 and a Voyageur 11.8. Note that both are 25" but the Raleigh has a 41.75 wheelbase the and Voyageur a strait 40". I can tell you that the Raleigh will be the beer buzz bike, the Voyageur the caffeine bike. I have found 43" wheelbases and you would be shocked at how comfy and forgiving they feel.
