After yesterdays century my partner and I are considering an aggressive sport tandem.
We usually hang out in the C&V section so naturally we were hoping for something with some miles already on it for a lower price.

The question:
How does the ride on a SWB tandem compare to a standard frame tandem?
Is it even worth considering or should we just look for a good "modern equipment" tandem and build it up to be more aggressive?

Also are modern SWB tandems even shorter older ones?

I have a family friend with a bike similar to this

and he doesnt ride it but is reluctant to sell it.
Should I make an offer or just forget this specific bike?
Thanks in advance.
