I finally got this one in the keg on Saturday, and after experimenting with high pressure and shaking, etc, I managed to get it to drinkable carbonation level by Saturday night. Sunday was much better though, and I have burped the headspace and reset the reg to serving pressure now - I've set it to give me around 2.5 volumes CO2.
Anyway - the colour is a nice copper / orange, and it is actually almost crystal clear above about 3 deg C. The H&G isinglass definitely helped a lot, I used it at -1 so it took a lot of the haze away. Also the beer pours with a beautiful creamy, white head this simply won't go away right until the last sip. I absolutely love flaked barley, I will probably try and sneak some into just about every beer I make from now on.
As for the taste, I have to say that this has to be one of my finest beers yet. It's got a deep, toasted malt flavour from the MO and vienna malt, with just enough crystal sweetness, and the bitterness, while powerful, is very smooth and soft and not harsh at all. There is almost zero yeast character, which is what I was trying to achieve. The hop flavour is incredible, and the aroma is pronounced. The beer also has an almost moussy mouthfeel to it, I think the flaked barley definitely helps here. All in all, everything works together perfectly and it is the most balanced, delicous, drinkable hombrew that I can ever remember brewing. I had about six pints of it over the weekend, I don't think it's going to last long! This will be a regular in my fridge from now on.
The pics don't really do it justice, my glass was frosty from the condensation and I couldn't quite get the camera to focus:
