Interesting that no hop was used at 60 or FWH - for a traditional American IPA (non-NEIPA), I would use a little up front for bittering (they are all pretty high alpha hops, so just a little goes a long way if used early). For me, probably the Chinook, saving the Simcoe for a little pine punch later as a flavor, aroma, or post-knockout addition (at your choice of zero, whirlpool, hop stand or mid-chill). You probably can't go wrong with those hops, though.
