  We consider the Sen limit of several global F-theory compactifications, some
of which exhibit an MSSM-like spectrum. We show that these indeed have a
consistent limit where they can be viewed as resulting from an intersecting
D-brane configuration in type IIB. We discuss the match of the fluxes and the
chiral spectrum in detail. We find that some D5-tadpole canceling gauge fluxes
do not lift to harmonic vertical four-form fluxes in F-theory. We discuss the
connection between splitting of curves at weak coupling and remnant discrete
symmetries.
