Hop schedule help: CDA/BIPA

I'm going to brew a CDA/BIPA this weekend. Normally, I am a big fan of the American C's, but am looking to experiment with some different varieties, and with a CDA/BIPA. The framework hop schedule is from Jamil's IPA in "Brewing Classic Styles".

Here's what I have:

.5 Simcoe/Centennial - FWH
1.5 oz Horizon - 90 minutes
.5 Centennial - 10 minutes
1 oz Cascade - 5 minutes
.5 oz Simcoe - 5 minutes
1 oz Amarillo/1 oz Simcoe - Hopback
1 oz Centennial/Simcoe - dry hop

Any tweaks or recs?

I don't want to agree with JZ. But this looks good. Personally, I go heavier on the end of the boil and the dry hop but I think this is a good idea to get your bearings on the style. Roughly for mine I do an ounce at 15,10,5,0 and 4 ounces for the dry hop two oz for two weeks and two for a week to freshen it up.

Thanks. I think I might sub Warrior for the Horizon but otherwise leave as is.

I used warrior for bittering in my last batch of BIPA and it came out really good. Never used horizon though so I can't pass judgement.

Yea, I've used warrior with good results. Also magnum.

Magnum is my go to bittering hop. Always good with that

Horizon can be used for bittering, but I find it to be a waste. It's such a high myrcene hop with a lot of total oil content and low Noble characteristics. It's perfect for late additions and dryhopping, especially in pellet form.

That said, Columbus (CTZ) and Chinook are my go to bittering hops. Myrcene doesn't count if you're boiling the hops, or adding them to the wort beyond 150-F ish.

Here are some decent level myrcene hops:

Apollo: 2.0 total oil / 40% myrcene
Summit: 2.0 total oil / 40% myrcene
Galaxy: 2.5 total oil / 37% myrcene
Chinook: 2.3 total oil / 37% myrcene
Millenium: 2.0 total oil / 35% myrcene
Magnum: 1.8 total oil / 32% myrcene

For a comparison, some of the best American aroma hops for an American IPA are:

Amarillo: 1.7 total oil / 69% myrcene
Citra: 2.5 total oil / 63% myrcene
Simcoe: 2.3 total oil / 63% myrcene
Horizon: 1.8 total oil / 60% myrcene
Nugget: 2.0 total oil / 52% myrcene
Northern Brewer: 1.8 total oil / 55% myrcene
Centennial: 2.0 total oil / 54% myrcene
Super Galena: 1.8 total oil / 54% myrcene

...and to a slightly lesser extent...

Galena: 1.1 total oil / 58% myrcene
Ahtanum: 1.0 total oil / 52% myrcene
Cascade: 1.1. total oil / 52% myrcene
Warrior: 1.5 total oil / 45% myrcene
CTZ: 2.5 total oil / 45% myrcene

Here's what I think I'm settling on:

1.5 oz (15.0%) Centennial (10.0%) - added first wort
1.5 oz (15.0%) Simcoe® (13.0%) - added first wort
1.0 oz (10.0%) Warrior® (16.0%) - added during boil, boiled 90.0 m
.5 oz (5.0%) Centennial (10.0%) - added during boil, boiled 10.0 m
1.0 oz (10.0%) Cascade (5.5%) - added during boil, boiled 5.0 m
.5 oz (5.0%) Simcoe® (13.0%) - added during boil, boiled 5.0 m
1.0 oz (10.0%) Amarillo® (8.5%) - hop back
1.0 oz (10.0%) Simcoe® (13.0%) - hop back
1.0 oz (10.0%) Centennial (10.0%) - added dry to secondary fermenter
1.0 oz (10.0%) Simcoe® (13.0%) - added dry to secondary fermenter

For a 6 gallon full volume boil / 5 gallon batch:

1.5 oz Warrior leaf or pellet (16.0%) - 90 min
2.0 oz Centennial leaf or pellet (10.0%) - 10 min
2.0 oz Amarillo pellet (8.5%) - 60 min hop stand between 100-150 F
1.0 oz Simcoe pellet (13.0%) - 60 min hop stand between 100-150 F
1.0 oz Centennial pellet (10.0%) - 10 day secondary dryhop
1.0 oz Simcoe pellet (13.0%) - 10 day secondary dryhop
1.0 oz Amarillo pellet (8.5%) - 10 day secondary dryhop

Any particular reason? Or stated otherwise, are you seeing problems with my schedule or is it just personal preference?

Most advice/critique on a recipe is typically someone's personal preference. I also value simplicity. It's funny see someone who is absolutely convinced that a 90/45/30/20/15/10/5/2/DH schedule in very weird amounts will give them significantly better results than a simple 60/10/0/DH. ~ not saying you do this, just making a point.
