The Quasi series has performance characteristics unknown in other lure designs.
The that stout head design incorporates an oversized 10 degree sliced face that produces a huge bubble trail over a range of speeds from 5 - 9 knots. This extremely dynamic lure is best suited to the short corner position in the pattern but also performs well when fished from the outriggers.
There are six sizes available in the Quasi series. The largest in the range is the gigantic XOS Quasi, ideal for targeting the biggest of fish on tackle built for the task, down to the Quasi #5, a lure that performs amazingly well on small marlin and sailfish.
No matter what size billfish you are targeting there is a Quasi perfectly suited to the task at hand.
