Best Sephora brush for under-eye powder?

[vivibcn]

I have the Laura Mercier Secret Brightening Powder, which I apply over my concealer in my under-eye area. What Sephora brush would be the best to apply it? I'm looking at the PRO Airbrush Concealer Brush #57 and at PRO Press Full Coverage Precision Brush #67 - are either of these the right ones, or should I be looking at others? Thank you!!

I love to use the #59 from Sephora for powder under my eyes. I find it's light enough to put the powder on but stiff enough to pack it on. Keep in mind that I'm top notch lazy and all my brushes have dual purposes. 😊 I think the other brushes are great for getting the concealer on but I prefer going bigger and fluffier for powder to avoid caking.

Thank you so much @RatchetOG this is really helpful! I want to avoid a cakey mess so lighter and fluffier sounds like the way to go.
