My 2 cents
The pro rib is approximately 1/4” taller at the rear (highest point) of the rib. The front is the same height as the standard TS rib.
I made the change because I was bottomed out (out of Adjustment) on the Standard TS rib and had a gap between the beads.
Now I have no gap, and now have a figure 8, and the same POI as I had with the Standard TS.
In my case it worked out for me, I was not looking for 120% POI, my POI is around 90%.
