Help with New Belgium Fat Tire clone…

[TimCA]

I was going to brew a Fat Tire clone recipe from the July / August Zymurgy (p 21). Ant how transferred the recipe into my Pro Mash and the IBU’s don’t come close to 20. In addition the first addition of hops does not have a time so I am assuming 60 min. And the Crystal malt has no L… Has this come up before? Do you have any suggestions? Here is the recipe for those who don’t have the issue…
Thanks
Tim

6.0 Pale malt
1.0 Crystal malt (L ???)
.50 Munich
.25 Biscuit
.25 chocolate

.75 oz Willamette or Hallertauer (60 min ??)
.50 oz Fuggles or KG (15 min)
.75 oz Fuggles or KG (5 min)


OG 1.050
FG 1.015
ABV 4.5
IBU’s 20

In case you are interested, here is the version I came up with and brewed last week. It is based on a thread on another board about the specialty malts in Fat Tire, combined with my own preferences. I don't think it will be a clone as much as an enhanced (read "better") version.
