Been using the Kuiu setup for a few years now with the BX-4s and it works for me. I like the setup with rangefinder pouch.
To be fair, I have not tried the Marsupial or Alaskan Guide Creations.
I think one of the best ready to hunt packages offered is the Bear Adapt 2 HP. The can be had for about 600. They have the updated Whisker Biscuit, but you could have it changed out if you desired for a drop-away. The bow is a very smooth shooter. This is coming from a PSE guy for the last 15 years.
