I personally find the coil upgrade to be the crossover upgrade that makes the most sense. Resistors next and capacitors after that. The reason the coil upgrade matters is it lowers DCR and increases damping slightly. It is subtle, but I think noticeable when used with flea-power SET amps.
As for getting components we don't stock, sorry, but we really couldn't do justice to that because we would lose our economy of scale. We offer stuff at such low prices because we buy so much of it. That means one-offs or custom orders would have to be significantly more expensive and it's just not worth it for either of us. However, you can buy the crossover board unstuffed and populate it with your own components if you want to.
