I've seen guys that kill the games playing either way at higher stakes, red line up or down. I don't even worry about it. I do know how to manipulate the line but I think in the passive micros it's better to be less aggro and just get paid more by made hands at showdown than trying to take away a ton of pots in non showdown style. Bet/fold will make that line stay up. any time your calling bets or Checking OOP with the intention of maybe folding later streets will destroy that line.
