Fan choices?

Now that deer season is wrapping up I am shifting focus to my dart. Last summer the car would get up around 190 but never overheated. This year I am going to try to make some modifications to knock it down a little. My question is what is everyone running for a fan. Right now I currently have the factory fan with a clutch but I was thinking of switching to the clutchless "performance" fan or possibly an electric fan set up. A shroud is another option but I have not been able to track one down for my radiator which is 27".

All other cooling aspects are operating as they should and my timing is at 16 initial and 36 on a .30 over small block with aluminum heads on pump gas.
