Solid at the bolt end. I use wiregates at the rope end, lots of people prefer bent gates

I carry one long 'draw and one alpine.
> * Is it a good idea to buy a set with wide slings? Guess that makes it easier to pull on it if you need to aid past a move or hang on it while clipping the rope in. Are those the main reasons for getting a wide sling?
Yes, definitely, grabbable slings are important.
> * Anything else to consider?
Keylock hookless nose on the bolt end is essential
