I first punched up a Buzz and used it for a few months.  With my slower ball speed during the summer months (and total lack of concentration), I decided to get the Hornet for dryer conditions.  Then early fall, I would go with something a little stronger than the Buzz, to round out a 3-ball arsenal.

The Hornet does exactly what LM says.  A tamer reaction than the Buzz and great length.  I determined that with my ball speed and revs that I would probably be better off with a ball between the Buzz and Hornet.  Looking at at WCR or Big-R-Bang for that spot.  (I don't see a lot of oil around here, except when I bowl in the American Masters, their conditions are tough!!)

15 to 10 with the Buzz sounds good if you have some hand and about 16MPH ball speed.  The Buzz will recover well with a strong, continuous arc.  If the Buzz is too strong initially, take it up to 1000/2000 abralon with polish, that should get you a little more length with no loss in backend recovery.

Where will the new Sting fit?  Stronger than the Buzz?

I agree with the backend potential.  I was able to play from up 10 to almost 10 out to the gutter.  Adjusting hand position and speed, it came back to pocket from all those lines.  Also, your typical LM hit, hard and nasty.
