Generally speaking, triceps respond well to lower reps and heavier weights. I like weighted dips and CG bench press for tris. I've also experimented with CG incline press and enjoyed that one as well.
My theory is that the triceps get plenty of higher rep work when I work my presses for shoulders and chest, so when I do a more tri-focussed movement I do it heavy. The key with any CG press is to not go too far in. Most people bring their hands almost all the way in. This limits how much weight you can handle which isn't good for the tris. I usually go either thumb from the smooth or middle thumb joint from the smooth. That lets me move fairly heavy weight but still puts the focus on tris.
