I really appreciate everyones feedback and encouragement. I have found that if I split my 3/4" strap down the middle, I can play either single or double strap. But, I prefer double strap. I can double strap and walk around and play all day--now my wife and dog can't hide from me. Also, I want to let Chris Miller know that I finally transcribed and learned Frisco Zydeco--a conjunto sound. Now if I can just get it up to speed. Thanks Chris.
I play all my cajun and tex-mex and Chris's Frisco Zydeco on my single row. I only play a single row. Chris was very encouraging and yes it can be done. My Martin is wet tuned 5 cents and I close #1 and #2 reed banks. You get a pretty authenic sound. If you dig a little you will find that the single row was used for conjunto in the beginning but soon switched to the double row. You can still find a few old timers like Wally Gonzales who play some conjunto on a single row. He also plays a mean toy accordion.
Two straps may not look "cajun" but if its any comfort the accordion is not "cajun". We "adopted" it back a few years ago. Like everyone says, nobody cares what it LOOKS like, its the sound that gives us the warm fuzzies.
I play with two straps(one over each shoulder) and center my thumb behind the keyboard. Been playing like this since 85 and I'm passing a good time.
