Sent 2nd go after cleaning holds at the top and sussing out beta. I just got back from a weekend at Hueco and I spent more time sending V3's there than I did on the opening boulder problem of this route. The opening of this route is closer to V3 or V4. Of course since it's only 6 or 7 moves that's still a pretty hard boulder problem to encounter on a route, but you'll find harder bouldering on Flinch or Grinch at Reimers. The opening boulder problem to Scorpion Child at Reimers is way harder, as is the opening boulder problem to Spanish Fly. The boulder problem start on this was about as hard as the start of Rain Dance. Considering that after the boulder start of the route you get a no hands, sit-down rest on this climb it's hard to include the difficulty at the end in the route grade since you can recover completely at the no-hands rest. So it's sort of like climbing a V4, then resting completely and climbing an 11b. With that in mind, if you only consider the difficulty of the boulder problem when calculating the grade of the route (since it's harder than the rest of the route and climbing the rest of the route can be done separately after resting) this thing clocks in at hard 12a, soft 12b. Certainly a boulderers climb, but it's just not as hard as any 12c at Reimers that I can think of. Apart from the grade, I want to point out that the opening boulder problem on this climb is insanely fun. It's too bad the landing would be hard to protect because it'd be more fun as just a boulder problem than the whole route.
Great opening moves through a V5 boulder problem to a big rest. From there, it's about 20 feet of easy climbing before reaching the final bulge where you'll find a pocket intensive crux in the 5.11+ neighborhood.
