Positives with regal-sound

It is of course very charming to embed a regal voice into the stop-list of a positive organ. But regal-pipes of the design I normally choose do only work properly if fitted with their own wind-chest.

So far I built two positives with regal-sound, one with 16foot in Waldheim, the other one, still unfinished with two voices as 16 and 8foot. Experienced musicians may estimate, in which way a positive is upgraded by such stops.
