Are you using a tripod with QR plates (Arca-Swiss or Manfrotto)?
You're probably aware, but BR makes a FastenR that will allow you to use the strap and your plate.
The Arca-Swiss system gives you much better L-bracket options and feet for long lenses - I find that putting the FastenR into a small 1" clamp (with a little loctite) makes the whole system work bettter, and I feel like it spreads the force a little more broadly as well as keeps me from constantly screwing/unscrewing the FastenR.
Anyway - welcome to the Dark Side!
