As I sit here scratching mosquito bites it is hard to imagine snow any time soon. It is a good idea to be prepared I suppose.
The problem I have had using the loader for snow removal on my long, long gravel drive is that it will dig. Float or no float, it will dig if I allow the bucket to touch the ground. When we get a bit of a blow I can easily get 30" drifts. This is when we bring the loader out. Some of my drive is through a 6' bank and there is nowhere to push the pile. Nothing like scoop and dump.
IMHO there is no substitute for a lightweight blade that will ride on the ground surface, the type that will collapse when you smack an immovable object, and that can be angled to put the snow off to the side. The loader will keep you out of trouble and it definitely has it's place but it is not the best solution.
As far as a rear blade goes, I don't have one, I have never used one and I can't imagine the blade being efficient if it is dragged instead of pushed. You need a fair bit of speed to make snow flow off a blade and speed can be awful when you hit a hidden obstacle if the blade is rigid. Others will not agree. Perhaps a lesson will change my mind. Just MHO.
Snowblowers have a lot going on inside and look to be high maintenance. Good for upstate NY. Pittsburgh is not upstate NY.
If you are going to use the loader be sure to get a bucket at least as wide as the tires.
All the best,
Martin
