Okay, so I understand the benefits of Pro-wings and am pretty sold on putting a pair on my 8' Fisher. My only ? is do they hold up to stacking snow? When I push into a pile won't these things get bent backward? How about if you hit a curb. If they won't hold up it looks like they come off easy enough to remove before you stack, but thats kinda like taking your plow shoes off and putting them on for different jobs. Is it a pain in the neck or am I just that lazy?
