Low D Kerry Busker and Metcalf Skellig

Has anyone had experience with either of these low Ds? How do they play?

I actually looked into the skellig a while ago but also couldnt find anything. So am curious aswell. The issue is I can only find things on YouTube which can sound much different than it sounds in person. It sounds much better in his burke comparison video than in the other that he compares it to his other low D, where it just sounds really plain. In the burke one it seems much quieter than the burke, and seems to have a big volume difference between high and low notes. I actually picked up a Metcalf low C a while ago that I saw on ebay and thought it overblew insanely easily, having a really quiet low end and really loud high end. Was not a big fan. He could have changed things by now though. I’m not sure if his other whistles play this way or not. His craftsmanship seemed top notch though and his pricing is quite good so I dont like to mention this issue, I dont want to make him look bad.

I haven’t played either, but apparently Seamus Egan was quite impressed with the Skellig he recently got from Nick Metcalf.
