So I got my bike out again today and put in about 18 miles (17.79). I rode with the new tires that I put on my bike a few days ago, the IRC Metro 1.5" slicks. I went through a couple different sets of tires (which can be viewed here:

These tires have taken almost a full pound of rolling weight off my bike and the ride is more responsive, faster, but not quite smoother. I feel more bumps and what not through the smaller tires, but the actual ride is smoother...no vibration and whatever else you get from bigger tires. I'll give another report after a few more rides
