Get a Lennox or sandvik blade.

I'm betting he doesn't want to spend that much.

Personally, I'm in agreement with you. (Blasphemey, I know, but I do not, nor have I ever, really cared that much for Starrett)

Point of caution.... 2, actually....

Regardless of the quality of the blade, you've got 2 things going against you...
73" isn't very long in band-saw years, and you're cutting through stuff that very likely has some grit embedded in the surfaces.

I'm going to guess that you're using a machine that doesn't have coolant? That would make 3 things.

....And how do you get a wheel into a bandsaw that uses a 73" blade,,,,unless you're talking a vertical, and even then....
