Mimi, I took some of your advice and lowered my tire pressure- a bit. The max said 105 and that's what I had them at. I lowered the back one to 100 and the front one to 95. The ride was nicer, and the bike seemed to be less skittish.

By the way, today i timed my usual ride again. There was still some wind pushing me around a bit, but not that strong. It seems my new skinny tires are clocking in not any noticably faster than my old fat tires. This does puzzle me, especially with such a big change in width, but it doesn't really bother me too much. They do "feel" faster, it's an odd thing. And I do notice the bike is a bit lighter in weight when I pick it up. Maybe my results will be better with no wind at all, just like when I timed the fat tires last. But hard to get a no-wind day to test them these days, it seems!

In the end, I am so hugely pleased with the buttery smooth shifting after my LBS tuneup that the tire thing doesn't dampen my spirit at all!
