I'm so thankful for you experts who take your time to answer these questions.

During my bike fitting, the fitter told me he guessed I would probably take another spacer out of my handlebar stem before the season is out. But, he didn't explain why I would do that or how I would know if I wanted to take one out. Any thoughts on that?

In the last few rides I've really started using my drops, and I'm much more comfortable with the road bike position, whereas when I started, it made me super nervous, since I was so used to riding a hybrid with very high bars.

At the moment my handlebars are exactly level with my saddle. I've lowered the saddle since my fitting - since I'm not using clipless, I needed to be closer to the pedals.
