Breiss Ashburne Mild?

[Braufessor]

Brewing a dark mild and trying to decide between:

1.) 100% Ashburne Mild as base
or
2.) 50/50 Ashburne/Golden Promise as base

Thoughts? I have not used the Ashburne malt before. The threads I found were somewhat old or did not have a lot of information on them.

Thanks
