Good luck with it and please keep us posted as to how it comes out. Trying to clone Big Wave is a noble undertaking indeed!
I have a kegged Blonde Ale right now that was also hopped with Galaxy and Citra (yep, the hops were inspired by Big Wave). I used Galaxy to bitter at 60, and then equal Galaxy/Citra additions at 10 and 0. No dry hops. The good news is that this is an awesome combination of hops. I’m getting a nice citrus/tropical/grapefruit thing that is just super enjoyable and a noticeable bitterness. The downside is that this has far too heavy handed a hop presence when compared to BW. Nothing wrong with that of course, the beer is still really nice, but I’d have to dial it back some if I wanted to mimic Big Wave.
