Just like Rusty said, just about any steak,I use them and also when I'm processing my Deer I'll sometimes just cut stuff into Jerky strips instead of grinding it.

On the marinades, it's hard to say there's just about every concoction out there,Id suggest experimenting, my main one is just teriyaki sause and Whorchestesire(sp) with sometimse garlic or seasoning salts.I'll cut up omion and peppers to add to the mix or a good one for fish is just 2 parts brwon sugar and 1 part salt.

If' you into experimenting try just a little meat at a time so if you don't like the way it turned otu you won't waste a pound or two.

Enjoy, I love to make jerky it's a blast.
