I'm reluctant to start talking about individual cases here (especially the 52) mainly because I don't consider myself fully proficient with the 52 flat spin.
Genna at Skytrace or Ian Austin will help you out. Personally, I feel that the risk is there BUT it is smaller than you might have been led to understand. It's far more likely with very aft CofG.
Get ACTUAL training with Genna or Ian if you feel that you are regulary exposing yourself to the dangers. I feel that the 52 is pretty naff at stall turning well...
