L1 1S or L2? Best fit for clubs?

We are a duet featuring guitars, flute and backing tracks.  We play wineries, brew pubs, clubs and restaurants.  Usually indoors, but occasionally outdoors.

I bought an L1 1S and love it, and it meets the needs for all the gigs I am currently doing, but I'm concerned that there may be an occasional larger venue where I'll be kicking myself for not springing for the L2 instead.

Any input, thoughts or considerations in making this decision?
