Thanks for the link. It's quite obviously a top end looker, and not having seen the kit close up, I'm guessing its top end components too. I can see little point in going for chrome or so called upgrade gold, which is just gold covered in lacquer. I always think that a premium white with gold accents look the classiest, or vice versa, and I know its possible to get a gold that is mixed with cobalt to increase the durability, rather than gungeing up the threads with lacquer.
I appreciate you've only got one shot at it in the first instance until development funds permit, so for myself I'd like to see rhodium or platinum with gold accents. I don't believe that Ti accents would look as classy, and if people are not prepared to pay a tenner for a top of the tree kit there is plenty of choice below it. A Baron by the way is about a tenner and a Sedona is even more. The Harvest to which Neil F compared the Alpha is about 13 or 14 quid. If you feel the Alpha is not as good as a Baron then get a cheap plating, but knowing your ethos and your attention to detail, somehow I don't believe that is the case.
