Recently announced magnetic models for four SPB and {\beta} Cep stars, along with magnetic detections for two additional stars, have potentially doubled the number of known magnetic SPB and \beta Cep stars (see Grunhut et al., these proceedings). We have reanalyzed the published data and re-reduced archival low resolution spectropolarimetry collected with the FORS1/2 instruments at VLT on which the models were based, and compare them with high resolution data from the ESPaDOnS spectropolarimeter at CFHT, investigating previously noted inconsistencies between results from the two instruments.
