IPA Partial Mash Recommendation

[tado]

I recently found a recipe for an IPA in Brewing Classic Styles that I particularly liked & decided to slightly modify it a little bit. Here's the recipe I am currently working with:

1lb Caramel 20L Malt
8 oz Munich Malt
4 oz Caramel 40L Malt
1.5 oz Carafa III
8 lb Light LME
.25 oz Galena (14.1%) - 60 min
.25 oz Simcoe (11.9%) - 60 min
.25 oz Amarillo (8%) - 60 min
.25 oz Galena - 45 min
.25 oz Simcoe - 45 min
.25 oz Amarillo - 45 min
.25 oz Northern Brewer (10.3%) - 45 min
.25 oz Galena - 30 min
.25 oz Simcoe - 30 min
.25 oz Amarillo - 30 min
.25 oz Northern Brewer - 30 min
.25 oz Galena - 15 min
.25 oz Simcoe - 15 min
.25 oz Amarillo - 15 min
1 oz Cascade - 5 min
.5 oz Amarillo - at turn off
1.5 oz Amarillo - Dry-hop for 10-14 days
.75 oz Cascade - Dry-hope for 10-14 days

I recently brewed an oatmeal stout using a partial mash for my first time and absolutely love how the head & lacing came out, which I figured was from the partial mash. Does anyone recommend doing a partial mash for an IPA? If so, is this recipe good enough or do I need more grains?

I don't know much about partial mash, I tried once, and my efficiency sucked. I will tell you that I think that is a lot of crystal. I have started using less than 1 lb usually 12oz split between crystal/carapils. I like a little lighter body, and usually brew 8+% beers. One other thing, I like a lot of late addition hops, my hop schedule usually goes something like this for an IPA... 1oz at 60,20,10,5,and DH

I usually like to have as much base grain as I have specialty when doing a partial mash. Nothing scientific, just what I like.
