Believe me I know. Use the brass crimp-on stops. This is great as it is small in diameter. Nonetheless, pack your riggers with at least 400' of cable. Most importantly have an extra spool of cable and weights on the boat, as well as extra snaps and crimps.
Crimps are sufficient to hold a snap on the end of the cable.
In other words you don't need fancy plastic ends. I have rarely broken a cable at the weight. Usually it breaks mid way down, due to fraying in the spool. Check your cable periodically during the day and if you find any frays cut and crimp the snap above the fray. The ones I like the best are the plastic push in type.
