Rule is three hooking devices per lure/device on a line/rod. You can have 5 swim baits per rig so long as there is only 3 that have
one hook. The rig ties to the line and is considered one device, three baits rigged with one hook each and two "teasers" (hook removed) should be legal. If all 5 lures had one hook or multiple hooks I am sure the warden would not approve.
Regardless of the number of points one hook is one hook.... be it single, double, or treble. Sabiki rigs are legal in pa so long as you cut them in half, giving you only 3 hooks. When fishing a Rapala F-18, F-13, or F-11 you have three hooking devices on one lure, adding an additional trailing hook for short strikes would make it illegal.
