BFR,
you say the wrist strap is "ALMOST" the same and you anchor the same. What do you use for your marker for your anchor?
How much different is Almost the same?
I am guessing 1/4 to 1/2 inch and it is just enough to put the bow in a slightly different place in the valley.

Just a guess.

Greg, the strap just fastens different but position and length are the same. It anchors in the same place and the peep lines up the same. I shoot from the wall so no difference in the valley. At 20 yds arrows from this release will be 10" left and 3" low. I will shoot one arrow in the bull with the Tru Ball, then one left with the new one. As I switch from shot to shot this way, I will have two very tight groups but 10" apart.
