RE: WGS speaker for a Mesa Mini-Rectifier 25-watt head

Does anyone have a recommendation as to which WGS speaker might be the best suited for a 25-watt Mini-Rectifier by Mesa?  I have a 1x12 cab that I will be using and I play no metal, just  primarily blues and 60-80s rock.  A side note:  the Mesa cab that is designed for it is loaded with Celestion Vintage 30s, but I am not wedded to a strict WGS replacement for the V30.

"primarily blues and 60-80s rock"

Sounds like Green Berets ... fur sure!
