Don't stick with just the 46 Normal and 46 Bear formations. The 4-3 Over can be really effective.
A good blitz to use would be 4-3 Over Mid Smoke Zone.
Reblitz the RDT, the MLB, and the LOLB. Place the MLB between the RDE and RDT. Place the LOLB between the DTs. 5 man rush, solid pressure, I prefer controlling the FS.
