I tweaked it myself the last time- used all maris otter instead of the 2-row and few ounces of MO. I don't know what 6 ounces did, either! That was in a recipe I found and so I kept that and changed the hopping. Yuri_rage changed somethings too, and that's in the recipe database. But I don't recall what he did.
I don't think the crystal should be in there, though. You want this to be all about the hops, with maybe a hint of malt (hence the maris otter) and no sweetness from the crystal. Still, it's your recipe and your beer- so whatever you decide is "right".
Edit: Yuri used crystal and a little carapils and left out the marris otter and he loved it. I used all marris otter the last time and loved it. I think you can't go wrong with whatever you decide!
