I guess it's a matter what side of the bed I get out from.

One of my frames is Tange 2. Sport touring geometry and 27"x1" wheelset. It rides predictable and stable. I don't have a 531 to directly compare but did build my brother's racing Triumph (Raleigh rebadge) for him. All 531 brazed in England. I thought his bike road very lively.
I couldn't keep up with him, but I don't think it was my bike's shortcoming.

IIRC, Tange 2 was more better compared to Columbus SP.
