Jeff I switched to a thumd trigger release 2 years ago and it really improved my shooting. I had a bad habit of trigger punching which has stopped since I switched. My anchor point did not change. Instead of anchoring withthe knuckle of my index finger tucked into the divet under my ear lobe Inow anchor with the knuckle of my middle finger in the same place. The one word of warning that I will give you is that when I lose concentration I have a tendency to let go of the release which can be disasterous. I bought a wrist strap so thatif that happens at least my release doesn't go flying down range.
