I've been using Proraso Green and Red, in tubs, for a while now and finally got a tube of Blue the other day. This got me to thinking, would their be any benefit to doing a super lather with the Blue plus one of the tub croaps? Obviously I would get the benefit of combining two varieties in terms of their respective additives (i.e. shea butter from the Red with Aloe from the Blue). Beyond this, are the formulations of the croap vs the cream different enough to have a net positive affect?
