The trophy taker is probably the simplest form of a fall away. It is easy to adjust and has been very trouble free. All of my hunting partners use the trophy taker and have the same feelings.
I think you are looking the right direction when you are looking at fall aways. My broadhead flight was improved drastically when I switched to a fallaway rest.
I tried the QAD, similar to the rip cord. I got rid of it, it does hold your arrow great, however in wet and freezing conditions it can be prone to not falling away. Just my experience, I am sure others might dissagree.
