Interesting Blog,
We purchased a Camp/House in Pickerel cove built in 98, the owner decided 150amp service would serve, my electrician agrees as I was suspect to increasing it to 200amp, it's not as much about 100/200 amp service as it is about what you intend to run at any given time in your humble abode.
Service amps provide the power to run the multitude of things you may desire at any given moment, the start up of say a frig/dryer/AC Unit uses far more power than it sitting idle, 30amp service would be hard pressed to run a busy household, and cold is in, lot's of cold needs lots of power.
