You're right about that elbow cuff, the closer I get it to my forearm (further down from my elbow), the lighter my SE becomes. My X1 probe straps are in the way though, I think I'll cut off the last one closest to the cuff, 4 plastic straps for the little bitty probe is probably at least one more than necessary. I also added those furry elbow cuff inserts, I don't know if they made a difference though.
