Depends on your rev rate and ball speed and the actual amount of oil.
St Flush is pancake core, resin covered balls made for the really dry lanes. More control than the Hornet.

Hornet has Buzz core and hard version of its coverstock. It is meant for light to medium-light oil. It gives easy, great length (probably more length than the SF) and it can have a strong-ish backend, again depending more on your release and rev rate. It needs a slight bit of head oil. While it is nowhere near being a skid/flip ball, it is mroe ball overall than the SF.

The Hornet can handle a whole lot of dry, but the St Flush is meant for really dry lanes, as long as you can still get resin through the heads. Polyester/plastic balls are the only step down from a St. Flush.
