You didnt say,but I assume you have a Fisher plow.I have 3 Fishers,I with a foil,I have no problems stacking with it,the only thing i dont like is that when piling snow,the snow will come over the blade and lay on the top of the foil.When you back up and drop the blade to start pushing your next pass,the snow falls off the back of the foil,down behind the blade,This makes it impossible to scrape a lot clean without going back over it.I waxed the foil and it helped alot,but it still holds some snow sometimes.
