Your pursuing SR shaving because you think it will lessen the irritation you get from other forms of shaving........I have to say, think again. I would suggest the DE route and a re evaluation of you shaving routine and products. Perhaps a open thread on "Irritation" is more to the point. There are people on here that have lots of different skin types so I'm sure a match for your problem could be found and a solution gained. Please don't take this as my putting you off SR shaving because that is the last thing I would want to do, but reading between the lines it's the irritation that is your problem not the shaving method.
