im sure ya would kill birds with both set ups ...... but if ya can get by with less decoys .... why waste time and effort settin out more than needed .... sum areas i hunt ill use 1-6 decoys .... other places ill set out 100 or more ....used 1500 in TX ..... but with the small groups of birdas ya seein there .... sounds like 1-2 doz would be plenty .......... good luck
