If you keep the pvc round, it is fair preformer. But, if you heat treated to say a flat recurve shape they are awsome. By heating and flatening them you can use larger diamater size and make a cutout shape handle for the riser for acurate shooting, plus it evens out the imperfections in the pvc. I have one made out of 1 inch pvc. Pulls 60lbs and been shooting it for 3 yrs now and it kept its draw weight. There are better wood fiberglass composite etc. bows out there but pvc when done right ( notice i said done right) definately can hunt large game and be accurate. If they had good pvc bows back in the day before firearms, they would have worked just as good.
