Congrats what a shot and trophy! I really enjoyed the video and watched it several times.
It seems to me that 65 pound bows, and even less, have been used on Cape and Asiatic water buffalo with success. There's a pic on Abowyer's and A & H's websites of a guy who killed a Cape Buffalo with a 58#@28" ACS. If I remember right, Ed Schleif of ABS shot his Asiatic Buff with a 65#@28" ACS. And I also seem to remember a few guys killing water buffalo with 65# DAS bows. It's obviously a good idea to work up as much as you can and not sacrifice accuracy, but I also wonder how often bow efficiency and draw length aren't factored into the equation? A 75# Hill bow may well be out-performed in terms of speed by a 58# ACS, or DAS, or Turkey Creek, etc.
Not that I have any actual experience in the area lol
It's a dream of mine and I've studied every piece of info about it I could get my hands on...so just a thought.
Congrats once again!
