Welcome Lefty,
I'm 6'1" and weight about 220 lbs. I put about 11,000 miles on my GZ 250 in about a year. It is definitely a better fit for us taller guys than the Rebel 250, which I have ridden, can't speak for the Yamaha or the TU. I wanted just a bit more leg room and I achieved that by adding about 2" of foam to my seat, which I preferred but that might not be your cup of tea. I think the GZ fits in there pretty well with bikes up to 600 cc or so as far as physically fitting your frame. If you want a bigger frame than that you'll probably have to go 750 or 900 size bikes or more. I found the GZ to be a pleasure to ride and easy to maintain. It handles well and for the type of driving you indicate, I think it would be a good choice. I'd still be ridding one except my circumstances changed and I needed to be able to put about 500 miles a week on something that could cruise at 75mph without pushing it's limits. Suzuki certainly sweetened the pot with that big price reduction, that is a lot of bike for the money. Good luck with whatever you decide, ride safely.
