Odd question, but all the time I hear people debating or just talking about seemingly useless information concerning lifting. For example, how many variations of curls do you see at your gym? I can't go a single workout without seeing at least 10 different types of curls. Preacher, standing, hammer, one arm, two arm, cable, concentration, back against the wall, curling a 45 plate with both arms. The list goes on. Another example is any cable machine with changeable grips. "Doing tricep presses with your hands closer will do this to your tricep, while doing them with this grip will do this to your tricep blah blah blah."
When people ask me what grip to use for tricep extensions or even cable rows, I tell do whatever you feel comfortable with and don't lose sleep over it. Same thing when it comes to curls, "what's the best type of curls for MASS!?!?" I say, do whichever style you want, there's no need to turn it into this big complicated issue.
It cracks me up seeing people spend an hour on the bench press doing every variation possible; flat, incline, decline, wide grip, narrow grip. Or when I see people hitting their forearms from every angle possible; wrist curls in front of their body, behind the back, with their forearm on a bench, etc.
Anyway, is it worth the trouble worrying about the differences in results from such slight differences such as what grip you use? I just hate it when people complicate lifting when it doesn't need to be so complicated.
