I've found I've learned the most when playing around with these combos, which is what makes Janda's book so good. I really need to do a lot more of it, rather than button mashing rake back promos on Party all the time.

I think your analysis suggests that exploitably betting big for value and with barely any bluffs is best in this spot, but betting weak suited kings for three streets of value is too thin. Have to say I find a bet check bet line will more likely get looked up by the bluff catchers in this spot, whereas a a bet bet line defines villain almost exclusively as Kx. Even though most regs know bet check bet is a value line, they still can't help themselves on the river.
