[10NL] Defending against cbets

Villain is fairly loose and aggro in small pots, 35/22/58 (steal)/86 (cbet) but I haven't seen him getting to showdown with anything too silly.

I would 3bet this often preflop, but called here intending to c/r when I hit a strong hand/strong draw as well as a lot of the time when I miss (especially with BD draws on good flops) and sometimes with total air on very dry flops. His continuing range looks pretty narrow here.

I think he will be continuing around 20% if I assume he started with any 2 half decent cards and will continue with sets, 2pairs, overpairs, OESD or FDs, or TPs JT+. In reality, I think he may even fold something as weak as JT.

Assuming c/r is ok, are we barrelling anything? I can't seem to find any decent barrel cards with FE. Even diamonds. (Even 10). The equity when called just about makes up for it if he won't shove low overpairs/strong draws, but it isn't great.
