So with goals of climbing big walls in the next few years, I have started to dip my toes into aid. I have been going to my local and setting up a TRS, and then using my cams and nuts to aid back up the hand and finger cracks. However, I want to learn more about the grappling hooks, beaks, and other pieces of kit that I would inevitably need to be familiar with. What would the best first pieces to pick up be, mainly for using them on faces without cracks for pro? Also, additionally, right now I am missing a few more aid specific tools, like an adjustable lanyard, harness with two belay loops, and ascenders. As I begin to climb actual aid routes around me, do I need all of that? Or are some things higher priority than others? Thanks!!
