Question, if you are from manila and already passed by SLEX, why do you need to exit at filinvest, then go to daang hari and have the effort to traverse the aguinaldo highway.

IMHO, the best route is SLEX, ECTex (ata tawag after SLEX) then STAR Toll then tanauan exit then go to talisay tanauan road. mas konti ang traffic. mas less hassle sa pagdrive. although may ginagawang kalsada ngayion sa may abndang tanauan batangas yung malapit sa st. caribrini hospital (nakalimutan ko name eh).

HTH.

Ligaya drive is asphalt by the way, AFAIK.
