ok here's what I did
04/19/2012
5 lb 2 Row
1.5 lb Flaked Maize
1.5 lb Vienna
1 lb Flaked Barley
1 lb Crystal 10L
2.3 oz Hersbrucker (2.6% AA) 60 minutes ===> I intended 2 oz but it was all I had left so I just went with it
0.5 oz Saaz (3% AA) 5 minutes
irish moss added with 15 minutes left
estimated IBU: 18.5
Wyeast Kolsch with 1 liter starter
Mashed at 152 degrees with 4 gallons
Sparged with 4.5 gallons 168 degree
90 minute boil with a little added water at the end to get a batch size of 5.5 gallons.
estimated og 1.050
measured 1.050
It was chilly during this week so I just put it near the window with a wet tshirt on it. It was at 60 for the first couple days. So I closed the window and it raised to 64 over the next 7 days. The 10th day I took a gravity reading and it was at 1.006. A little drier than I wanted it to get but oh well. I cold crashed it and racked it into the keg the next day. This was 15 days ago.
Now that I can taste them side by side I think I have to go with the opinions of the others who have attempted; I like mine better.
that being said, they are very close. They are both crisp and have that fruity tang right up front. My brew has a little more spice to it, and I do have to say that mine tastes a bit grassy at the end, which I suspect could be remedied by using little less sazz(or by using hallertauer instead of hersbrucker, which I now realize lends grassy flavors as well). They are almost identical bitterness wise, but I would still say that mine is a little bit stronger, so I could probably reduce the hersbrucker to 2 oz, to aim for 16 IBUs compared to the 18.5 I got. Mine is darker, but not by much. Mine is also cloudier, which is unusual given how clear my ales have been lately. This leads me to wonder if the flaked barley is to blame, as I have heard others tell about its potential for cloudiness.
If I were to attempt this again I would reduce the barley to half a pound, and probably use a bit less saaz adding it at flameout instead of 5 min(or just use hallertauer instead of hersbrucker). Mash at 154 to 156 for a higher FG, aim for 16-17 IBUs, and I probably wouldn't do anything about the crystal cause I like it looking darker anyways.
BTW they both are a bit clearer than they are in the pic
