In the rocks or on the reefs or edges of the reefs I think the jets and tru-trips shine. I say this because if your leads must be longer than the water depth, and if you must slow down or stop to net a fish, make a turn or to avoid another boat the in-line or snap weight will sink and can snag in the rocks since it is further from the boat than the water is deep (example~~30 ft. lead in 20 ft. of water) = Murphy's Law!

Jets and tru-trips both tend to float up or stay neutral in those conditions so I only fish with the divers anymore so I don't have to change back and forth to fish on the rocks or open water and some days I will fish both on the same pass. As for jets and tru-trips off of small boards I have had no issues with either the regular Jet 40's or the tru-trip 40 divers at speeds as high as 2.5 GPS. The small boards are much easier to read with tru-trips than regular jets because once the tru-trip diver releases/trips the board pulls entirely different even with a small fish hooked. I use the Church Tackle TX-22 boards.

In open water I think they are both about alike, the difference depends more on the configuration of the weight as the configuration can change the tracking and action of the preferred lure.
