Hi! I agree that Hoola is a great bronzer for contouring, but i would suggest a smaller brush that will dispense the product a little better to the hollow under your cheebones for the contoured effect:
an angled blush brush would also do the trick:
I personally really like contouring. I think it adds beautiful dimension to the face-if done right. For contouring, a matte bronzer is great, but you have to make sure that there is ZERO orange undertones. For example, Benefit Cosmetics Hoola is great, along with a brush that is slightly tapered but not too big. A great brush is the SEPHORA COLLECTION Classic The Complexion Brush #53, which is super soft.
Hope that this helped you!
I agree that the Benefit Hula is a great product for contouring. You always want to make sure that you are using a matte bronzer because, it will look the most natural. I put together some other matte bronzers that you can also use.

I also recommend using a slanted brush to make contouring easy! Sephora Collection I.T. Angled Synthetic Blush Brush
