If you do a similar count down Brass launch once you have the product in hand it will sell out fast. This will work especially well if you change the advertising on CPF and temporarily substitute in the Brass light for the Aluminum light highlighting limited quantity. After the initial 20 or so owners create a buzz on CPF with pictures and reviews, add an awareness building countdown to product launch - maybe two to three weeks - and it will be done.
This will work because, as you know, many HDS owners like immediate gratification -- light in hand within a few days of purchase....
(In my opinion, this is a customer type segment (mindset) distinct and different than the pre-buy and wait for the light to be made segment)
