Keeper Advice - Thielen vs. Allen

I’m in a 12 team PPR league that allows two keepers. I’ve got Kamara locked in at the 14th round. All summer I’ve been leaning toward Thielen in the 10th, because I’d be crazy to pass up that value right? The thing is, I can also get Keenan Allen in the 3rd which has me doubting myself lately due to his crazy ceiling and potential growing pains for Thielen.

What does the Foot Clan think? Thielen in the 10th or Allen in the 3rd? Thanks in advance.
