Appreciate all the advice. Narrowed it down to the Cowbell 3 (comes in a 46, 12 degrees flare), FSA Adventure (found a 46cm, 15 degrees), and Origin8 Gary Sweep OS Handlebar (15 degrees, not sure of exact width but wider than the other 2).
Leaning toward the Gary but I'm going to see if someone local has it in stock - I want to make sure the interrupter brakes will fit.
