Thanks for the link. I'll be sure to read all I can.

After I posted that I realized that there are so many different variables that could possibly affect the shave, which might lead to irritation.

I cannot shave with a DE two days in a row. I think that's worse on my skin than shaving with a SR on day 1, and a DE on day 2.

Thanks for the tip on experimenting with different angles. I have noticed that my angle tends to be a little greater than it should be at times.

About a month ago I started an experiment where I'm only shaving WTG, and only one pass to see if that helps, and it certainly has. It's just not that close of a shave. But at least it's eliminating some possible causes of skin irritation. Now I just need to work with the same method until I don't see any skin irritation for 24 hrs. after shave #2.

Thanks for your input. I really appreciate it.
