I just believe a build style page is an easier method to try and configure something as you have the image of the saber in font of you immediately as most people cannot think in 3D or are able to put their ideas down on paper. If they program *snap to fit* parameters on the build page when selecting and piecing together sections or some other method to show you that your chosen item will or won't work with others. That way you're not simply trying to imagine something in your minds eye.
If you choose the route of emailing and waiting for a response of whether or not some parts will coincide with others and then continuing on from there; it will be a long back and forth process which could take weeks or months to figure out as some questions will lead to others and also if parts you had in mind don't fit your original concept, then what? This is mainly my reason for suggesting this as I've tried to have an email conversation regarding build ideas using production saber parts but emails of "will this work?" and getting "no" in reply but waiting several days to receive it was taking far too long to conceive a build. To add, always sending emails merely for possible build ideas would only congest the already full email stream that SF receives that should be used more for sales and customer service.
When you can instead do a build online in your spare time within minutes or spend hours day dreaming and build several saber ideas if you have nothing better do. You see your product immediately in front of you along with a parts list and cost. LEDs and Blades are already in the accessories parts list; add those to your order too and you have your warrior tier. Sending out a box of parts may also cut down on lead times pending quantity and availability of sections as you shouldn't need to wait for assembly. Grab part 1S, grab part 2A , grab part 3B, grab 4E and 5R, throw in a box and send out to client. Don't warranty the build but warranty parts like if threads are chewed or bent and will not allow sections to join, etc.
