I am hoping for some comments on my planned Dizzy Donkey Special Bitter recipe before I get the brew going, hopefully over the weekend. Don't hold back - all comments are welcome as always!

I have deliberately gone for slightly lowish BU:GU ratio as most of my beers so far have had a ratio of 0.8 or more and I want to see how a beer will taste with a lower ratio (this one is around 0.6). Beersmith estimates an FG of 1.012 (although I wondered if the Windsor might stop higher than that) and 4.9% ABV.
Looking forward to hear your opinions - cheers.
