I agree with moving the 30 minute addition out to 0. I'm very intrigued by Jarrylo. I've done an all Zyghis IPA with a whole pound. It didn't do much for me, but it was by itself.
When first looking at the schedule, I was nervous about the columbus. Normally I'm the guy that puts the absolute stamp of approval on columbus in APAs and IPAs, but if you really want to taste these hops as is, it can be invasive of their flavors. Then you switched it to simcoe. Simcoe is strong, but I find it better to blend with others. Columbus, to me, adds another addition to as opposed to blending with other Hops. I think these beer with be good.
As far as IBUs go, I just had Deschuttes Red Chair NW APA. It's 60 IBUs of cascade and centennial.... Freakin amazing beer.
