Very much on target I'd say. And it's well worth comparing your sail inventory vs. your polars, in order to determine what hole(s) you're looking to fill. Especially if you're making an either or choice, based solely on the purchse of only a sail. However, if you're looking at the whole hardware setup, then things may be a bit different.

Start with the polar diagram for your vessel and that will tell you the relative performance for wind angle and wind speed.
I have both and I use the CZ far more frequently. It fuels on its own luff so it can be left up, though it is easy to drop and re-rig.
What Kestrahl stated is very much on target, & true; on all counts.
With some adjustment to the hardware
, you can run a Code 0 on a spinnaker furler
. Although it isn't an ideal setup. The reverse isn't true however. Meaning that you can't rune an Asymmetric
kite on a Code 0 furler.
And yes, as stated, for a true Code 0, you need a Lot more luff tension 2:1 or more. This being that due to their original design, Code 0's are meant to be used as a light air, upwind sails
(primarily). Though they can be used through some range of reaching angles. But not flown (efficiently) anywhere as deep as an Asymmetric
is designed for.
One other thing worth considering, is the price
of hardware/furlers required to run either type of sail.
Generally, Code 0's are setup to be run on furlers, almost exclusively. So in addition to the high cost of the sail, there's the high cost of a very much, purpose designed furler for it as well. Plus, a 2:1 or greater purchase
on the halyard
, or tack fitting.
Where as if you get any type of spinnaker
, regardless of what AWA it's cut for, you can fly it sans; furling gear
, & even without sock/snuffer. Or, you can buy furling gear
for it, but this also requires an anti-torsion cable also.
The trick/catch being, that for about the price
of an anti-torsion cable, you can get a dedicated snuffer/sock for it. And thus, still be able to fly it short-handed, but for a LOT less than if you try & run it with furling gear. Or than it's possible to run a Code 0 with or without furling gear.
I've queried a few folks about their top down furlers, as well as snuffers. Plus done some inquiries on Real (as in racing
type) Code 0's. And it seems that unless you plan to race
, the consensus is, that you're likely better off to get the asymmetric of your choice with a sock for it.
If you want to do some reading, in terms of what I dug up, I posted a SERIOUSLY in depth
questionnaire on Code 0 Furlers over on Sailing Anarchy Forums
(my handle's the same there). And also, there's a thread there on Top Down Furlers.
Between all of those, plus me asking some in depth
questions of folks with; Top Down Spinnaker Furlers, Code 0 Furlers, & Spinnaker Snuffers on here, that's where the above conclusions came from.
