Villian is a reg - 679 hands 20/17/7 . - hand is 13days old so not fresh, but i still think the turn is a call as the population can fire one street with missed draws. River I'm unsure; 67 got there and he has 55,44 in his range, i feel population under bluffs OTR but I don't block the spades.

Discounting a4&a5s, he has 8 value combos and a 12-15 spade combos 40:60 value:bluff, however i think the population rarely raise flop and double barrel bluff.

what would you do here?
Is my thought process flawed anywher?
given its 60% vs 27% should i call?
If his cbet is 29% are we more likely to see a value heavy range from villian and should easily fold?
