fin setup?

Another fin question. I’m getting another swallowtail made. This time a 8’2’ x 22" x 15" tail.The width of the swallow is 7.5" It has a single concave through the tail. My question is wether to get a straight trifin setup, or go with a 2+1 setup? I’m not sure how small a board a 2+1 will work. Thanks

2+1 [ if it were my board] … with front [side] fin systems , because I would probably ride it as a single fin 90% of the time .

…that’s just me , though .
