I do think it's useful to explore alternatives (and I do have to give Saurez credit for being willing to do that in spades!)...I used to consider 2 guns just a little bit of overkill. Now it seems normal to have the LCP in the left-hand pocket and the primary carry gun, these days an SR9c, in the strong-side holster.
Lots of times we do a "test," carry something for a day or so — and, boy, am I guilty of that particular sin! — then declare that to doesn't work for us. Habituation to anything out of the ordinary takes time!
