One of the nice things about purchasing a used Alembic is that if you take your time and get it for fair market price, you're pretty much safe knowing that if it doesn't work out for you, you'll get your money back (possibly less shipping, etc). I'd worry far more about the taper, nut width, string spacing, etc and less about a 'chunky' neck. Chunky necks can always be reshaped to fit what you want. In fact, for years, Stanley Clarke had his tech reshape the necks that Alembic built for him until they finally convinced him to just let them build it to his specs. Pretty sure the 'Dragon' feature custom details that story.
