I like the addition of the wheat in the grain bill!
You are using 1/2 oz of hops in the dry-hop. That leaves you with a half-ounce leftover, right? I'd either throw that in the flameout addition, or would go ahead and dry-hop with a whole ounce.
Pardons if this is incorrect - maybe you have these hops around already and that's the amount you have. If so, all apologies.
TTTT, I'd split the Simcoe & FF7Cs and use half ounce of each at 20 minutes, then a half ounce each at flameout, but that's just me. I am probably too late, anyway.
Regardless, it sounds great, be sure to keep us updated!
