I like elk!
Sounds like you did your job well, congrats on the deer.I’ve only shot mechanicals. Well I’ve only shot one mechanical at an animal. Great huge hole at 15 yards. Didn’t get a pass through but I hit high on the shoulder. Arrow still penetrated enough to hit the opposite shoulder but not go through
My point of mentioning whether or not you’ve shot broadheads was mainly because of the..if it ain’t broke don’t touch it.
You don’t know yet, so an answer can’t be given such as that.
Personally I’d spine up, bareshaft tune and use a quality fixed head.
