SLCDs are gonna set you back no matter what kind you go. I have a full rack of BD, augmented by metolius TCUs, some Tricams, and of course, all sorts of passive gear. Go with what feels good to you. I like all my gear, and it is all useful, so I have no preference either way for Spring loaders Just make sure the pro you're using feels good to you while your feet are skating out of the crack, your power's fading, and your last piece is 15 ft away. Fun fun fun!
