First off. Use 4 ascenders! If it's real aid that is what you will want. Try top stepping with only two aiders. It is very hard to stand there with one foot in the highest rung and clipping your next peice. As for hooks. I have 2 cliff hangers, 2 pointed cliff hangers, 2 talons, leeper flat, leeper pointed, metolius hook(not that great), fish hook, captian hook. I would like one more fish hook to add to the list. I like the pointed cliff hangers more than the regular. Bat hook holes are too shallow. And why spent $30 on a removable bolt when you can use a $10 hook. To get free hooks, look at the base of walls. Go with petzl ascenders. Or clean with one ascender and a gri gri. I haven't tried but will soon.
