Years ago, I was all about using a bar attachment, whether straight, cambered, or the V-Shaped one. It allowed me to move more weight, which at the time, I honestly believed was all you need to concern yourself with if you wanted to get huge. Eventually, I stepped back and realized that even though I was moving 'big weights', and yes, had fairly good triceps, I still didn't have the polish (and I don't just mean low bf%) that the guys in the magazines had.
I read an article on 'POsitions of Flexion'. While I think a lot of it was just bs, it did get me thinking about the '3 positions' you could hit a muscle with (midrange, stretch, and contraction were the terms I think). I started to look at the exercises I was using for each musclegroup, eventually trying to make certain that I was taking advantage of each possible scenario. What I came across (and still use to this day), is this series of exercises:
1-Rope Pressdowns- Yes I still use heavy weight, but I concentrate much more on getting a great squeeze at the contraction point. Also, doing these early on serves as a pre-exhaust technique
2-Skull Crushers -I used DBs for a better angle on my wrists, but these serves as the 'stretch' portion of hitting the muscle. By eliminating the possibility of extending your arms perpendicular to the floor, you can keep constant stress on the muscle as well.
3-Bench Dips - As a 'finishing exercise', this is your basic, compound ('midrange') movement. Whatever's left in the tank get used.
Only if something's bothering me will I deviate from this approach. ie. If my shoulder is acting up and I can't do dips, I'll do pressdowns with a bar trying to mimic the movement as best as I can.
That's my thinking on this anyway
