I'm kinda new to Metal Pless, so I can only say what I have experienced, I have a Plowmaxx 8-36-14 with live edge , plow ways about 2,300 lbs, Fireside, you are right ....you have to dial it in just right, and if your loader has kickouts, for settings etc life is easier.
There is a learning curve, these are not cheap plows as you know, so went for the top line, I saw the base model, I looked at HLA snow wing, talked to someone that had a snow wing and sold it to get a live edge and wouldn't go back.
Since tha, t I am aware HLA has a "flex edge", I don't know how that is or compares to MP. I will say MP Paint seems to hold up better then HLA, again my two cents. Maybe your shows keep wearing replace or maybe have carbide made instead? I have not plowed slush yet....
Everyone has a budget ,I always suggest investing that kind of money, always ask people that have them, pros and cons, like anything else....
