Just the original 100gr regular Slick Trick 4 blades.
Glad to hear that.
Many hunters have been over-marketed "larger" heads on the premise bigger is always better.
But generally speaking, the smaller the broadhead, the more accurate and the greater it's penetration, especially when it encounters large bones.
Decades ago, I spoke with an accomplished elk killer who used a very small 3-blade head (which I don't think survived all the marketing for larger heads). If I remember correctly, this head was only 7/8" in diameter. I simply asked why such an expert archer & accomplished bowhunter was using those tiny things.
His answer was enlightening:
1) Unlike larger broadheads, these tiny ones always provided complete pass-thrus, which he felt was a big deal to insure recovery.
2) Smaller heads were more accurate, and less likely to plane from wind, a bad release, or simply nicking some vegetation.
3) Shot placement is more critical than inches of blade.
Hit the deer in the right place, get a complete pass-thru, and you should recover that deer.
Will also add he was shooting a compound bow (not a crossbow) where there was more likelihood of a bad release effecting arrow flight, and a bad release can really throw off the poi with a large broadhead.
But one other thing stood out.
He said that by going to a much smaller head, he could then fletch with much smaller feathers, and that greatly helped to retain downrange arrow velocity, which in turn greatly flatten trajectory beyond 40 yds.
Remember, elk are a much larger animal than a deer, and a high-probability shot can be made at greater distances. I'm also thinking he had just killed a big bull at @ 80 yds, and got a complete pass-thru with those tiny heads!
It was also about this time I was shooting a 1 1/2" diameter head for which anything less than a perfect release, the poi would move 6 inches at 30 yds! Went to a smaller head and never had much more issue with less than perfect releases.
