depending on customers requirements and mods we may fit a low temp thermostat, too low and fuel economy suffers, oil may not protect as it should etc.

Forged pistons, that's another debate but piston to bore clearances are probably the biggest deciding factor in that car

I wouldn't expect the fans to run on the freeway, there should be enough ram air to do the cooling without the need for the fans. Of course if the fans were on before freeway speeds they would stay on until the threshold that switches the fans off.

My BF temp is normally a little under half (3/4 between the first temp mark and half), at half is where my fans are normally kicking in, once fans are on the temp drops very quickly to the normal level again.

Velocity,

You asked if the OP had just done a coolant change. I was just curious as to why you asked as I have just done one and have noticed needle sitting slightly higher.

If you use too much coolant your engine won't cool as well as running the right mixture. Nothing cools better then straight water, and coolant is not very good at transferring heat. If your using premix I wouldn't worry about it.
