I remember when Feisol legs did not have anti-rotation because they said it was not as strong. I assumed that anti rotation required a notch or hole or something that could weaken the leg.
Then Feisol went to anti-rotation legs, I suppose because of market demand. (They say they still make the rotating kind for anyone who wants them). Do you see any difference in strength now that you have the anti-rotation sleeves? I have the old type on my CT-3442, and it's not a big deal, but anti-rotation would give a little less to think about, especially when I'm in a hurry setting up.
