Tsunami Stout (Pelican Brewing)

I'm pretty interested in brewing something very similar to the Pelican's Tsunami Stout. This will be my first jump into all grain having only brewed extract with specialty grains in the past. I've also never taken a stab at making my own recipe before so I'm looking for some feedback as I haven't been able to find anything out there that looks convincing yet.
I'm working off of a stout recipe from my LHBS and tweaking it to use the ingredients listed on the Pelican site.
I'm not the best at describing beers but this is a creamy stout with a thick head and a forward chocolate flavor. Not very hoppy so I've cut down on the hops a bit. I'm assuming that the chocolate flavor is coming from the chocolate malt but if that's not going to get me there, I'd appreciate some feedback on that as well.

Here's my first try:
10lb 8oz 2 Row (Pale Ale Malt)
1lb Roasted Barley
4oz Black Patent Malt
12oz Chocolate Malt
4oz Flaked Barley
3/4oz Magnum
1/2oz Willamette
WLP041 - Pacific Ale Yeast

A couple of notes;
I'm intentionally trying to keep the hops to a minimum because I want my wife to like it as well. Their site lists the yeast as "Pure Ale Yeast" so I'm not sure if maybe California Ale Yeast might be a better option? Pacific just sounded too good.

Anyway, please blow me up if I'm crazy or if there is something out there that I missed.

Thanks,
Steve
