  Type Ia supernovae (SNe Ia) are important cosmological probes and
contributors to galactic nucleosynthesis, particularly of the iron group
elements. To improve both their reliability as cosmological probes and to
understand galactic chemical evolution, it is vital to understand the binary
progenitor system and explosion mechanism. The classification of SNe Ia into
Branch groups has led to some understanding of the similarities and differences
among the varieties of observed SNe Ia. However, partly due to small sample
size, little work has been done on the broad-line or 02bo group. We perform
direct spectral analysis on the pre-maximum spectra of the broad-line SN
2019ein and compare and contrast it to the core-normal SN~2011fe. Both SN
2019ein and SN 2011fe were first observed spectroscopically within two days of
discovery, allowing us to follow the spectroscopic evolution of both supernovae
in detail. We find that the optical depths of the primary features of both the
CN and BL supernovae are very similar, except that there is a velocity shift
between them. We further examine the SN 2002bo-like subclass and show that for
nine objects with pre-maximum spectra in the range -6 -- -2 days with respect
to B-maximum all the emission peaks of the Si II {\lambda}6355 line of BL are
blueshifted pre-maximum, making this a simple classification criterion.
