Well...just my 2 cents, but...

I have only been straight shaving for 6 days now and I refuse to use anything else. Here is why.

On the first shave, I barely managed to shave 30% of the areas I wanted to shave (I have a goat)...I intentionally left the shag everywhere so that in subsequent shaves I could monitor my progress. So far I have made great strides on every session.

This is one happy unit typing

as always YMMV, and there is probably no wrong answer on this one.
