Will there be any alternative colours/materials for the weight?
Unfortunately, there isn't much that competes price-wise with clear coated brass. After thinking over possible options (stainless, cerakoted brass, etc.) and their cost, it was decided to run a single weight option.
E white is electrophoresis I believe? Does anyone know what the finish is like ? Is it easily dirtied and scratched ?
It's a matte white. Some KBDfans boards have it, such as the recently stocked e-white Tofu. I'd assume it'd be a typical matte white surface, in that it won't hide any grime.
There is any limitation on the number of boards that will be made? My only fear is that I miss the cutout, if there is any, especially since there is so much interest in this.
The group buy is unlimited, so as long as you don't miss the GB period, you should be fine.
