My only comment is that many subsequent experiments have not been able to discern any apparent benefit from the FWH method, such that it can in essence be treated the same as hops added for the full boil, which they are. Nothing special about FWH from what I can tell.
If you're gonna do it, why not split a batch 50/50, with one having 100% FWH, side by side against another batch where the hops are added in traditional fashion and boiled for like 60 minutes. My bet is that if you taste them blindfolded, you won't taste any difference, or if anything, the FWH beer might taste very slightly more bitter.
