As you can see, it is a mixed bag. The benefit of shaving 2 handed is that there are less types of grip/stroke combinations to learn-- whatever works for the left side of you head will work for the right side, with the other hand.

It was actually pretty easy to learn with my left when I started, because the whole act of shaving with a straight was new-- so my dominant hand really did not have much of an advantage. Probably the longer you wait, the harder it will be to learn.

Once you have the strokes down with confidence, then you can probably gravitate back to 1 hand if you wanted to...
