The Prolines are significantly better than the Personna Blades and give a much smoother shave.
I would certainly delay your decision until they arrive.
Better still are vintage blades or the modern Chinese Schick Blades (if you can get hold of some for a decent price). The Chicks transformed my experience of the razor significantly. [emoji846]

You prefer the Schicks to the Prolines? Truly, ymmv!
