Thoughts on Walsh Convertible A/D Smallpipes?

Any out there play them?

Looking for impressions from owners. Mouth or bellows blown, delrin or blackwood.

I have been interested in getting a set of these for a while but would like to know more about them. I currently play Uilleann pipes so would more likely get them fitted with bellows.

Any thoughts or experiences with these would be appreciated!

Thanks
Scott
