We attempt to define the structural properties of Broad Absorption Line (BAL) QSOs and their relationship with the general quasar population using the Eigenvector 1 correlations. We identify 8 low-redshift quasars (z < 0,5, 6 with a BALnicity index > 0 km s^1) where it was possible to combine optical and UV spectroscopic observations. The special utility of low-z quasars involves our ability to discuss CIVA1549 BAL QSOs in the context of the Eigenvector 1 optical parameter space and to have a reliable measure of the quasar rest frame. We find that the majority of the BAL sources are population A sources as defined in Sulentic et al (2000). At least 2 sources that are hosted by ultra-luminous IR galaxies show intriguing effects in their nuclear spectra A possible correlation between the terminal velocity and luminosity L also suggests that the luminosity to black hole mass ratio (L/M) is a governing factor with the largest terminal velocity BALs showing the highest L/M values. The CIVA1549 emission line profiles of classical BALs show the ubiquitous El population A blue-shift that supports a disk-)-wind scenario with an opening angle of < 45° Observation of "secondary" BAL features roughly in correspondence with the mean radial velocity of the CIVA1549 emission motivates us to model the BAL systems with an additional component that may share the BLR outflow and may be co-axial with the accretion disk, perhaps associated to a significant black hole spin.
