) Flipper block: Big fizzle for me. DW Forum said it worked great for them.2) Stalk block: This has produced some great blocks for me on safetys and corners. We have gotten 8 second blocks in practice. But on ILBer's, another big fizzle.3) Drive (hands) block: This is what I started with. Must not have worked too well because, afterwards, I tried everything else.4) Shoulder block: This is common for me to teach my backs because my HB and WB are usually smaller than their opposing LBer.5) Screen block ("Get in the way" or, as one coach told his team when he couldn't stop it, "Don't worry, guys. They're just running a whole lot of blockers through a great big hole."): Has some great moments. Requires perfect timing.6) Rolling Block: If you ever want to see a LBer just get completely taken out of a play (as in pancaked), this block will do it. Unfortunately, the blockers seem very timid about using it.
