Mid range is not too hot - that can be a product of the 195 thermostat vs a 180 stat. Near the top of the swing by the H is when it is running hot. As long as it comes back down, you will be fine - change the stat to a 180 if you are really worried, but don't run without a stat - it will actually run hotter that way. You may want to flush the radiator out to be sure it isn't full of sediment and crud.
