Aaahhh...Drake Boinay skis......my cousin who lives out in Denver tried his buddy's r-models A-Basin earlier this month. They were size 178, flex index 26. Thought they skied very well...stable, fast and very damp. He did think, however, that they were very pricey and were not so special as to warrant the cost. After researching their website, I'd have to agree. According to the site, they offer different flex options for several lengths in their three models. More options than usual, yes...but custom? Not really.
Being a former surfer, and having a brother who is a snowboarding enthusiast, custom should mean more than just offering flex options for given legnths. In surfing, and now in snowboarding, it's possible to get a board that you specify exactly...no one will ever have a board exactly as yours. "Custom" in skiing should be similar to that...custom side-cuts and dimensions, constuction/core options, "flat" or with binding system integration, graphics/colors as well as length and flex. Yes, ski manufacturing is complicated and costly, but full-on custom can be done. In comparison, it takes much longer to custom shape and finish a surfboard, while custom snowboard makers are employing techniques that are very similar to the ski manufacturing process.
In short, as my cousin told me, the db skis were really very good. But as far as being better than top-shelf, off the rack Volkls, K2s, Rossis, etc.? He didn't think so. You probably could buy just as good for far less.
Their US demo locations are quite spase, but they say they'll post a list of shops you could demo through...try before you buy.
