I was taught to climb "closed system", tautline hitch right off the tail of my saddle tie in. I wasn't climbing full-time then, so it was a while before I first saw a split-tail system at an arborist supply store.
My first thought was, "Wait a minute, this opens my system to a potential failure if I don't clip the 'biners on properly, I mean I would have to be drunk or blinded by raccoon pi$$ for that remote possibility to happen, but there's the weak link, not sure I like this." But I bought a couple of 'biners and a six-foot split-tail with a spliced eye and the rep showed me the "new" Blake's hitch.
First time I climbed on the split-tail, I knew there was no going back! So much faster, easier to advance my rope up the tree that I even stopped bothering to throw my line so bleeding high, why waste that time when unclipping and advancing is so easy!
Then I saw another climber taking up slack one-handed. How? Micro pulley! Nice, I want one, got one. No looking back now, I bought another for my lanyard.
Now I was actually actively looking for gizmos. What is that shiny bit on the rack over there? A Pantin? What's it do? $70 bucks!!? Yes, I'll take one, please. I use it all the time, wouldn't want to be without it, footlocking is bad, bad ergos.
Then I bought a Petzl micro-cender and a twisted clevis to go on a new steelcore lanyard. I really wanted to love that thing. I mean, how cool is a machined from billet alloy, anodized block of eye-candy? It would look at home on a Boyd Coddington machine. But the first time I used it, I saw it's flaws. Clumsy on the slack takeup, at least with a steelcore, but worse yet, to release slack, I had to un-weight it, annoying. But I was sold on the gadgets, I stuck with it, stuck with it for three months. Finally I binned it and I'm back to a Prussic and pulley on my lanyard. Easier, smoother and three months too late.
So there's good and bad with gadgets, but I'm still sold on friction savers, floating false crotches, adjustable false crotches, ascenders, they all work, all have their applications in the book of climbing techniques.
