I've only flown mine three times and never without the ATN sock. I would say the sock is very, very handy.
Pratical Sailor December, 2004 issue rated three snuffers. Their summary:
*The ATN is most rugged, most expensive, has lots of good features.
*The Chutescoop is cheapest, lowest weight, some questionable features.
*North's SnufferPlus is their preference for its lighter weight and cost versus the ATN.

I have the standard Mac/Doyle spinnaker. I moved the jib block 12 inches above the standard jib/forestay tang so the spinnaker would not interfere with the forestay/furled headsail. I guess this also allows using the headsail while the spinnaker is still hoisted and snuffed. Or, with a pole or two, one could even run wing and wing with chute and genoa. The genoa is 206 sq. ft versus the main's 151 sq. ft. Don't know how you could see where you're going though without a Crow's Nest.
I shackle a 6-inch SS 1/8" cable pendant with a snatch block on the forestay deck tang for the spinnaker tack sheet which leads back to the cockpit. The pendant slides around the furler drum without wearing.
The chute does move the boat nicely. I need more experience with it.

Any news yet about Roger's extendable bowsprit?
