Ok, I understand what they are and i understand you can pretend it's a SR, and don't need a strop but...

They require or tolerate (as I understand it) completely different angles than SR, so they're not really good training for using a SR; and
They use blades equal to or the same as DEs...

So, if you want to wet shave, why not just use a DE or go straight to a Straight razor (pun not intended). You can buy a good shaving SR from Whipped Dog or through the classifieds, strops don't (necessarily) cost a bunch and you'd be learning the real deal.

I'm not criticizing, just asking.
