Sunshine is harder, the hole is about 2/3 or 3/4 down on the right side, the only real option at this level. Boof to the right.
Sledgehammer is Easier. The horizon lines are more pronounced but you are moving slower and should have time to adjust as needed. You may still want to stay left at the bottom to avoid Clarks Hole. It's not terrible at this level, but can still catch you by surprise if you are not expecting it.
Wallslammer has the couple holes against the wall (right side) at the top, but if you stay left you can avoid all that. In fact, the farther left, the easier. If you hug the left side, it may even feel like class II+. (Boring, but gives you time to enjoy the spectacular view.)
Don't even worry about Boat Eater hole. It's a big rock.
"So in two seconds, away we went, a sliding down the river, and it did seem so good to be free again and all by ourselves on the big river and nobody to bother us." -Mark Twain (The Adventures of Huckleberry Finn)
