I need to test it going downhill, to see if it shimmies much.
No worries!
My '74 Raleigh Comp has both a long wheelbase and a huge amount of BB drop (8.5cm by my measure). I would say it does everything compromisingly well, with the exception of very high speeds (>46mph). Once I spin out, I pretty much have to press one knee to the top tube to damp out the vibration. My 2001 Spectrum Ti, OTOH, does everything UNcompromisingly well, including high speeds. It has a much shorter wheelbase and a higher BB.
