The last few years I've been shooting a 51# hybrid T/d with axis 340's and 100 grain inserts and 125gr heads. Total arrow weight 560gr appox. With 2 blade stingers I've gotten 2 pass thoughs (broadhead out the far side). Last fall I shot a cow at 35 yards with a wensel woodsman elite and got a complete through and buried in the dirt on the other side.
A few years back I shot a 6x7 at 25 yards with a 50# recurve and axis 400 arrows with stinger 2 blade. Total arrow weight 460gr. After the shot I saw the arrow pushing the far side, but it did not break through.
All these elk fell in sight, but I would't hunt with that last setup I mentioned again. It worked, but I've seen first hand what a arrow that weighs a little more can do.
That being said your setup will work great if you use a well tuned arrow that has at least some moderate weight to it. And as far as broadheads. I think any of the ones you menioned will work.
Just choose what you have the most confidence in.........Figuring out what to use is half the fun
My choice this fall will be a 250gr vpa. I've never shot anything with them yet, but the reviews are tops!! Worth a try in my book.
