Clone recipes are rarely accurate to the real thing, or don't even resemble it, except for a catchy, similar sounding name.
It's not just the list of ingredients that makes a recipe, the methods, the process of brewing make all the difference. As homebrewers, we can't replicate the breweries' processes, while small deviations throughout the processes yield different beers when homebrewers brew the same recipe.
So relax, brew the recipe as close and well as you can or see fit.
Use a yeast you can easily obtain, suits the style of the beer, and most importantly, enjoy the results.
The Chico strain is a very good yeast for West Coast Ales/IPAs, and every yeast manufacturer offers it under their name. Safale US-05, Mangrove Jack M44, Lallemand BRY-97, etc. are pretty much the same (dry) yeast.
