Does anyone have an issue while clipping the rope? They seem small. What about with double ropes?
Fine, but not great for a single rope. Can't speak to use with a double. Most small carabiners don't have great gate action, but they'e shaped well to hold the rope without any problems.
I wouldn't use them for sport draws, but no issues with single or twin ropes. Clipping speed isn't usually the thing holding you back on trad.
