I play in a country band and do not use a Dbl. pedal with them. However at home I work on the the Dbl. pedal more than anything else. I would say get one and fool around with it. When you gig and don't need it, use a single like I do. They don't have to be high dollar pedals either. I used a I.C. Jr. for a long time, and liked it just fine. I've also played some inexpensive Pearl Dbl. pedals that were provided for me at rehearsals. They felt pretty good also. You can use a Dbl. pedals main pedal as a single also. So you don't have to have a single and a Dbl. pedal. Leave the slave unit at home when you don't need it. Kind like cym. I might have a lot more cym in my set up at home, but not with my band. Go for it.
