The XP24 comes standard with a rubber scraping edge. To me, that is the one downside. I also had a rear blade (Woods HBL72-2) where I installed a conveyor belt edge from rubberwearstrip.com (IIRC), and I honestly was never happy with how it performed, and ended up putting the steel cutting edge back on. My driveway is paved asphalt, and I use my box blade on the rear of my machine. After I have pushed all the snow where I want it, I go back with my box blades steel cutting edge, and scrape the remaining layer of ice. I did the same with the rear blade when I had it. I've yet to experience any damage to the paved surface directly related to the steel edge. I did have a rock/pebble get lodged in there once, and it did leave a drag mark for a few feet. But there is zero tell tale signs of a steel edge scraping along the asphalt, on my driveway. My experiences using both rubber and steel edges, says the steel edge risk, is worth the reward.
