I'm 6'3" and got a 58 cm. I love it and think it is perfect for me. However, I'm not built like you normal 6'3" person as my inseam is barely over 33". My torso and waist are really long and I have normal length arms for a person around 6' tall. My 58cm frame with 32" standover gives me more than inch but less than two. I also prefer my frame on the slightly smaller size, however the 60-61 wouldn't even allow me to standover the thing without my dangly bits nestled on the top tube. So I can't imagine how you could go with a 60-61cm frame. I would think the 56 or 58 depending on your dimensions and preferences.
