Just to follow up, I rode my bike with the 130mm stem and I love it! I have a seat post with a set back, and I was able to really tune in my cockpit fit. I can get ultra low in the drops with the flared bars when riding slicks on the flats and I have decent upright positioning when riding on the top/hoods. I'm able to do fast sprints with my back near horizontal to the ground and dig in when riding uphill trails. I'm about 5'7, but I really like riding low to cut as much air resistance as possible.
