I just got a Frontier 1072 rear blade a couple of weeks ago. These have been discontinued in favor of the 2072.
My JD dealer recommended the Land Pride instead of the 2072 because he believes the 2072 is inferior to the 1072. However, he was able to locate a 1072 in inventory elsewhere and get that for a good price.
Don't know how much this helps, but if two JD dealers agree, can it be wrong to go with Land Pride? I'm sure you will get all sorts of folks recommending all sorts of brands. If you aren't penny-pinching and want to save yourself a headache, the Land Pride is a safe bet.
I took the 1072 for the color and "discontinued" price. If I had to choose between 2072 and Land Pride, I would buy the Land Pride and a gallon of green.
