In regards to choils, I prefer larger ones to elf choils, but I'll take no choil at all over a large choil. This is main reason I passed on the Mud Mutt.
That heart shot with a 4 moa red dot from 80 yards is impressive, rest or no rest. What optic were you using?
I've gotten very used to the large choils...on the mid-size blades, at least...4+". Not sure why...it just feels natural to me. I like my short little GI's for hunting needs, without any choil for certain. They are 3-3.5" range, and with a purpose (but could certainly be used otherwise).
I haven't been able to warm up to the CABS. Maybe it's too long to be without a Choil for me, and my grip doesn't naturally fit with the no choil? I don't know. If it had mudder grips, and not black paper full tang...might be a completely different story!! The profile is great...but I still put the Bog Dog above it on my list. Of all things, like that the BD doesn't have the nuclear meltdown treatment also.
Aimpoint T-1....sitting on my quiet little BCM.

Only change recently, my Dad got me a BADASS selector for Christmas, that I promptly installed. Liking it
