Forgive the redundant question or concern but.........I've used sched 40 PVC on a front and rear blade for several years and infrequently have shattered a piece or two off when I hit an iceberg. After reading the above posts, I went today to buy a piece of ABS pipe. I'm a novice around pipe but, just by holding the ABS in my hands, I can't believe that ABS will be more durable than schedule 40 PVC when used for blading snow in icy conditions. Can someone who knows something about pipes chime in (again)?
