I have had great results using Abbey strains with this in combination with a few different bretts and blends. The bretts that work best in this base would be the "funk" driven yeasts such as Omega Bring on the Funk, Bootleg Biology Funk Weapon #1, Wyeast Brett Brux, Wyeast Brett L, and a long aged BSI Drie. Co-pitching with lacto brevis will give you a firm acidity (not overly sour) in 4-6 months.
I'm planning on brewing this up again soon with some ester heavy british strains.
So far all of my batches with this have been without fruit, but darker fruits such as cherries (1.5 lb per gallon) and even raspberries (2 lb per gallon) would pair up quite well with it This base is great for a quick afternoon brew with a fair amount of malt character in the finished product.

This version turned out fantastic. Oloroso Sherry, Oak, Tart and Sweet Cherries, and Tart Cherry Juice have really rounded this beer out. The ph at bottling was 3.55.
