@jsqt I have had some Transparent Ultra G5 for a couple years and am currently comparing to some Shunyata. I have swapped them about a dozen times over the past few weeks so definitely feel your pain. I would kill for some bananas haha.
I get them snug with my fingers and then hold the cable with the spade as close to vertical as I can while carefully tightening the terminal with a wrench. Be very careful to not over tighten as breaking the terminal off would be a major mess to fix. I do it a little at a time and then test the cable gently to make sure it is secure and then come back a few min later to make sure it didn't loosen.
