Buzz is earlier and more angular than the Hornet.

Sting is stronger than the Sure Strike. The Sure Strike is slightly longer and stronger than the Buzz.

The Big-R-Bang, according to Lanemasters' website, should be the "longest and strongest" of them all. On the other hand, some folks have seen otherwise.

Basically, you are looking at:

Sting - medium-heavy, decent length with power-arc + heavy roll
Big-R-Bang - medium, length with backend
Buzz/Sure Strike - take your pick, light-medium, length with assertive move
Hornet - length plus arc for drier and/or shorter patterns

I'm no expert, but from what I have seen and experienced, this is how it goes.
