Lesser absorption/sensitivity on thighs?

Hey guys! For the last 10 years or so. My infusion set always went on my stomach. That being said, there's a lot of scar tissue! This morning I've decided I would use my thigh to switch things up. I was under the impression that new site meant more hypos and sensitivity. To my surprise, my BG has bit a bit high all day. Do any of you find the absorption isn't as good on different part of your body?
