Steering still feels a bit light not sure if this is due to the more upright geometry of the hybrid or not.
You reported what most others have reported. A few like their tires rock hard but in reality their loosing performance on street use due to the tire actually hopping or skipping over road imperfections, rock hard tires only work on very smooth surfaces like a velodrome and even there you don't want them to hard due to loss of cornering traction. Sheldon Brown I believe talks about the fallacy of using too high of pressure. And that Michelin calculator formula had been around a very long time, I used the formula back in the 80's! We had a chart instead of a calculator.
The steering feeling light could be the bike, it could be the brand and model of tire, tire width, if it's a new bike you may not be use to it yet.
