New La Bella Golden Alloy Flatwounds

You can generally use a plain steel F string to complete any 7 string set.

I'm not aware of any bass ball end or length gold colored plain strings.. actually.. Aurora has gold plain steel... They are closed till after New year's but I should be able to make that single happen.

Yes I know high-F plain string can be interchangeable across brands but we're talking gold color scheme here, and I've just checked your website, there's no Aurora singles as an option and their sets don't even have as high as high-C string.

They have them. Like I said... I have to get with them after the new year. They are closed for the holidays.
 
From what I understand the initial offerings will not. The only flats from La Bella that will fit a "Dingwall" with a 37" B-string are ones I had made. It would need to be something similar to that. If I see enough demand I can make it happen.
I'd buy a set that would fit a long scale Dingwall at first opportunity.

Aside from that, know if there are any plans for extra long scale?
