Well, I like the idea but that seems a little low on the hops if you want a SMaSH IPA. Could get away with way more on the back end and then a dryhop addition too. For IPAs I like a 15, 10, 5, 0 and then a dry hop. Could use a half ounce to an ounce for each. Never used the Ringwood Ale yeast, says it has fruity, malty complex flavor so that could add to a SMaSH brew if you like that description.
I hate Walder Frey...
