In this thread I saw no mention of partitioning attack

In the past the Mixnet networks that allow several
 visible parameter to be chosen by the user (i.e. Mixmaster)
 was considered vulnerable to partitioning attack,
 that can make traffic analisys easier, lowering
 the anonimity set. The parameters can be some non-default
 remailer properties, some fixed user-chosen chains, or the
 location diversity in Autonomous System domain.

I read that is generally agreed that traffic analisys
 is the main road to attack low-latency systems like Tor.

It is possible that give a lot of hand-configurable
 parameter and stressing the necessity of a personal,
 "smart" choice (exit router enter router forbidden router
 and so on) this can make traffic analisys a lot easier
 respect a no-user-configurable-parameters situation ?
