Go for the whipper.
Look no further than DMM's Brass Offset Free Package when you're climbing through a series of micro-placements and not much else. These three brass stoppers boast a high breaking strength to give you peace-of-mind when you're running it out. Their offset heads make it easier to place in flared fissures, and the aluminum swages flex for the fall and bend back in place for the next route's whipper.
Offset brass heads
Set it! and Forget it!
Familiarity: I've put it through the wringer
Love me some brass!!
When things get small, and flarey, and a bit gripping, pop one of these bad boys in and wrench on it - it may get stuck for life, but your ankles will thank you later as you sail to the chains instead of rocketing into the dirt.
I bought two sets of these to have a good amount of brass betwee me and the ground!
