Looking at the BiS list, I could agree with your true BiS if and only if it was to be confirmed that acc cap is in fact 482. I have always heard that is 472 and haven't found much of anything to dispute that.

If the cap is 472 then the allagan wrists with valor gloves is BiS but only because of the extra 1 parry and dropping your acc to 479. Personally I will be going this route until I can really get into T5 and see where I stand on misses etc. As of right now I sit at 477 with food and don't notice misses at all.
