Nah!!! Don't go with monolights. The large drawback is weight. Separate "heads" are far more comfortable on stands and booms, and, unless you go for the sophisticated stuff, are more easily controlled from the power packs themselves.
That said .... you could easily get into a powerpack/ monolight argument - as easily as -- *more* easily than ...photographers arguing over the "best" film / developer combination to use.
