Hi ChrisO, I heartily agree about the not using treble hooks.
I grew up on the water and still live on it 24/7.
Treble hooks are nothing but a blasted nuisance and catch more fisherman than fish. They always seem to hook up on everything else other than fish.
I remove them and replace with doubles as they are FAR LESS likely to catch YOU or the boat.
I suggest putting some red shrink tube on shaft before/after attaching split ring, as the ring can slide down and off hook.
A piece of stainless or Monel wire will do same. The red tube does attract fish. Red wool trailing from lure also looks like blood and excites fish as well..
Only issue I've had with the doubles is hooking up to big Mahi mahi which can crush them flat with their top palate.
We have lost a lot of fish when trolling with trebles before converting to doubles. Keep those hooks SHARP. Unless they are chemically sharpened OR you do it yourself, most hooks are simply not sharp enough out of the shop. Using Vaseline on them will slow rusting process. YES, even stainless steel points rust very quickly. (same day)
