I think it's a great line to take IF u have seen villain raise his position. If you have no read on villain aren't sure there's a decent chance he'll bet his position you could be giving any draw juicy odds to smooth call.

Edit : that being said, it's not as if you min-bet it or anything... I'm not a fan a varying your bets all that much to "protect"... So 1/2-2/3 pot is fine.
