[FT] Are Submunitions Packs overpriced?

Well, just been thinking...

A SMP is MASS 1, COST 3

For the MASS of 1 of them you could have a B-1 - ok, its only 2/3 the
range, less damage at all ranges, and is affected by screens - but it
has 6 arcs, can be used every turn, and doubles as a week PDS.

For the MASS of 4 of them you can have a B-3 or a Pulse torp, B-3 is
twice range and can be used once per turn (but OK, it is affected by
screens), Pulse Torp has +12mu on maximum range and does more damage,
penetrates armour, and can be used once per turn.
Or you could have a SMR - also 1-shot, but 2-extra arcs, +6mu extra
range (+another 6mu lock-on), _lots_ more damage, but needs skill to use
and can be stopped by PDS and/or fighters.

So, what are peoples experiences of using SMPs?
