You've got long legs!!!! I'm 6'0", but only have a 30.5" inseam (I'm short legged/long torsoed)
You could probably ride the 19", but you'd have to swap out the stem for a shorter one!
Personally, due to my BMX background, I like a smaller frame than I should be riding. I should ride a Large, but stick with a medium.
