Fat % in Hamburger for beef stick

[mrad]

What's the highest fat content you would use for beef sticks?
Whats the lowest fat content?

I have always used 80/20 but have not been able to find it on sale this summer. This week I found 73% lean for $1.99 and 86% lean for $2.69. I'm wondering if one is too lean while the other has too much fat???

A little cooking math lesson.
A pound of 73% lean, and a pound of 86% lean mixed together makes 2# of 79.5 % lean. Close enough to 80/20 to do what you want.
Your cost would average out to $2.34 a pound.
Enjoy the beef sticks !
