My WR2 is 1.05 and I can only be satisfied with the result of shaving it when I make three passes (WTG + XTG + ATG). But three daily passes hurt my skin after five days in a row, so trying to get an equal result using only two passages (WTG + ATG), I tried shim this week.
I used cut Feather blade for the wedge.
At first I tried only with one blade (theoretically turning my WR2 to 1.15) but, being very honest, I hardly saw any difference in effectiveness, the result didn't satisfy me.
I then tried using two shims (going approximately to 1.25).
So I got a better result but it still hasn't satisfied me with two passes.
I will not try to put another shim. After these tests I wonder if just adding the two shims will make WR2 1.05 really behave like a WR2 1.25 ....
I don't know if adding shims changes anything from the blade angle to an original 1.25 ...
I don't even know if an original 1.25 would be able to meet my goal of making only two passes
Anyway, I will use my WR2 again as original (1.05) and doing three passes with each shave.
