You need to have _very_ different path parameters to cause TCP
noticeable problems (and then if one of the paths is that bad
you're screwed up anyway).

Most of asymmetrical paths are quite "symmetrical" parameter-wise.

Maybe in a perfect world, but given that all ISPs are not created equal, it 
is usually the case that the two paths don't have the same latency and packet
loss characteristics.
