From Dave Harrison, the creator of JB Signature Lures:
"The JB Signature Lures Cruiser is a plunger shaped head with deep front taper towards a slanted nose. The nose is fairly small because of the deep taper and has a slight scoop added to the profile. Comes in three different sizes in Small (7"), Medium (9"), and Large (12"). Catches many different species including Mahi Mahi/Dorado, various species of Tuna, Wahoo, and Marlin as well as other Billfish.
This asymmetrical shaped and keel weighted lure is based on a modified profile of a real baitfish. With proportions somewhere between a plunger and a bullet with an angled face and a gentle scoop, this weapon has a very realistic swimming action that rips the surface when it breathes. With an ideal trolling speed of 7-10 knots in all conditions the Cruiser will still swim great up to 15 knots on those calm days. Originally designed as a long corner lure it also runs great on the riggers."
This particular head is the Medium size with 9" skirt saddles. This color scheme comes in a "Skipjack" theme with an iridescent purple back with tinted black stripes and silver body with black "Skipjack" stripes along the bottom of the head. The entire lure head has a beautiful rainbow-iridescent hue to it - Photos cannot do any of these lures justice. Skirted in purple/clear with a pink lateral line over plum.
