I just took a quick look at it. Might be something to try. Looks pretty good. One question I would have though, being so high gravity would two packs of yeast be advised? I have only tried a starter once and it failed to get going, so if two packs of yeast is better then I will go for it that way.
If you use the 1450 in the recipe, either 2 packs or one and a starter.
