Here's a trick I discovered: While using Recoil Jump to cling to a wall, it is possible to slow your descent significantly by spamming the direction of the wall. The timing for this is pretty forgiving since you'll remain in place for a moment every time you re-cling to the wall. This technique could prove useful in Ship L-229 or in the fight against Atom. I estimate you can fall almost 4 times slower with this method!
