Recipe looks like a solid, tasty ipa.
only thing i might consider doing would be to either increase dry hop time or have a couple different dry hop timeframes
ie dry hop .5oz simcoe, 1oz amarillo days 1-5,
.5oz simcoe, 1oz amarillo days 3-8
something along those lines. I've had great success doing that with my ipa's.
no necessary changes though. like I said, it looks quite tasty.
Good Luck!
