I believe both that you mentioned are fall away rests. I have read a lot of good things about fall aways but I just don' t like the idea of having another moving part to have to rely upon. They may be great, but mine works just fine too. I use a NAP Quicktune 3000. I love the ability to micro adjust the rest to help fine tune my arrow flight. I' ve had mine for 3 years and the silencing material on the prongs is just now starting to show a little bit of wear. It may not be the perfect rest for everyone but it' s worked well for me.
