Plz help me developing a turn c/r strategy

[recallme]

I was told by someone here that i play uncreative and would like to change this, especiall vs good regulars!
I hope that you can say with which hands this particular play is best or if a simple bet is just inferior.

Game is 6handed and Nl2k, 100BB effective.

Hero raises to 70 from UTG or Utg and is called from Co or Bu. Rest folds.

170$ in a HU pot now.
Flop is:
Ks8s2h
Hero bets 140 and Villain calls.

Turn: Td 450$


I would like to include a c/r here into my game, which should at best be balanced between made hands and semibluffs

Hero`s range: AK/65s/88/AQ

A c/shove would be a small overbet most of the time and everything else looks stupid i think.

I did some math, if i c/r with my major draw Villains "calling folding ratio must be "1 call:1,75 fold"

Do you like mixing in a c/r with these hands and if yes, which one would you prefer?

PS: If you are uninterested or want to flame me, plz Pm me pr open up an extra thread and link it in here, but plz don`t spam this post.
I really want to improve my game and hope that some of you help me.

Thx
