I won't argue that one is better than the other but I chose what suits 
my situation best.  I'll respond to some points below.

Agreed but I think the analogy is a bit stretched.  But, in particular, 
I haven't seen any need for the mix and match and of the three 
photographers I know well who have packs and heads none of them mix and 
match anything.  But it you need it you know what to buy.

No big deal.  Alien Bees are inexpensive and can be added to in even 
smaller increments.  Small lights can even be upgraded to bigger lights 
for a $25 upgrade fee plus the cost differential between the two power 
levels.

Alien Bees cases are made of very tough plastic.  If you want to move up 
the quality chain you can buy White Lighting brand.  Similar and more 
rugged stuff, both designed and sold by Paul Buff.

I've had stands blow over twice outdoors.  Fortunately, no damage either 
time since the umbrellas took most of the impact and were not damaged 
either.  (good Photoflex umbrellas).  Some flash heads do cost less than 
an equivalent power Alien Bee.  But some flash heads cost *way* more.

Not true of Alien Bees.  A typical Novatron head (which is fairly light 
weight compared to some) is 2.2 pounds.  The Elinchrom heads weigh 
between 4 and 5 pounds.  The largest Alien Bee, the  B1600 (640 watt 
seconds) weighs 3.7 pounds.  The ones I use, the B800 weighs 2.9 pounds. 
  The B400 only weighs 2.5 pounds.

Yup, you can be sure I'll correct you since it only takes 15 Alien Bee 
B1600's (at 640 w/s) to deliver 9600 w/s at a total cost of $5399.95 for 
new equipment.  I would use my 15 lights spread out along the blimp to 
achieve a more even light :-)

I don't have any of that stuff but I've never needed it.  My mind is 
drawing a picture of a 4800 w/s hair light igniting the hair of the 
model.  She'll probably be ticked.  :-)

Sorry, that didn't compute for me.  My clients are too busy schmoozing, 
eating and drinking to pay any attention to me or my gear.

The actual reason I use monolights, and specifically Alien Bees, has to 
do with safety in dark dance halls, flexibility and ease of use.  With 
packs and heads there has to be a power cable stretching between the 
pack and every head.  It almost invariably means stretching across some 
doorway and having to use gaffer tape to keep people from tripping over 
cords.  With a monolight I can generally find a power outlet nearby the 
light stand.  It's much rarer to have trip hazards.

Packs and heads (unless extremely expensive) are typically limited to a 
couple of discrete power settings and/or power ratios.  Some even 
require care in setting up lest too much power be applied to a single 
head and blow it up.  The Alien Bees are infinitely variable over a 5 
stop range and power output can even be controlled remotely for each 
light individually via wire or radio transmitter.

Lightweight, inexpensive and extremely versatile monolights work for me. 
  YMMV, of course, and probably does.
