In Clone Brews, they have the SNPA using Nugget (bittering), Perle (flavor) and Cascade (aroma).
In reality, SNPA is made with Magnum, Perle and Cascade.
I had already used the Nuggets before hearing about the Magnums. The brew turned out rather well, if I say so myself. Nuggets or Magnums would be a good choice, though go with Magnums if you want more of the SNPA taste
